Hey rebel solopreneurs 🦸♂️🦸♀️
Are you frustrated by making the same business mistakes over and over again?
You risk wasting years of effort and thousands of dollars if you keep letting your gut make all your important business decisions (especially when it comes to creating digital products that actually sell).
Thinking, fast and slow from Daniel Kahneman will help you understand your two different thinking systems,
so you can stop making costly bad decisions and start creating online courses and templates people actually want.
Just like Scott Lang (Ant-Man) had to learn when to trust his instincts and when to slow down and think things through,
you too must master both your fast and slow thinking to succeed as a digital entrepreneur!
Ready for better business decisions without the mental traps?
Let's jump right in!

🍹 The book's core solution
Two Thinking Systems
You'll discover exactly how to recognize when your fast thinking is leading you astray and when to activate your more logical, deliberate thinking system.
This leads to fewer expensive mistakes, better digital product creation decisions, and higher profits from your online business. Holy smokes, who wouldn't want that?
Daniel Kahneman was a psychologist who became obsessed with how people make decisions.
He wanted to figure out why smart people kept making the same types of mistakes over and over.
The crisis hit when he realized that all the economic textbooks were completely wrong about how humans make choices. (The economics professors nearly fell out of their tweed jackets when they heard this!)
His ideas challenged decades of economic theory that claimed people were logical decision-makers.
· · ·
BREAKTHROUGH! Kahneman discovered our brain has two completely different ways of thinking.
He realized economists had been studying the wrong thing - people aren't as rational as everyone thought.
His big insight was that most of our decisions happen automatically in our quick, emotional brain system without us even realizing it.
He called these two systems "System 1" (fast, automatic) and "System 2" (slow, logical) thinking.
· · ·
Working with his research partner Amos Tversky, he created a new theory called "Prospect Theory" that changed how we understand decision-making.
Kahneman's work was so revolutionary that he won the Nobel Prize in Economics in 2002 (pretty amazing since he never even took an economics class!)
He became one of the most influential thinkers in psychology and economics, with his ideas changing multiple fields.
· · ·
Time to explore if Sam, a solopreneur can use these ideas to go from making costly business mistakes to creating successful digital products!
Here we gooooo!
📖 The story: Sam's journey to decision-making mastery.
Meet Sam:
His idea: Creating online courses and templates teaching small businesses how to set up automated marketing systems.
His target audience: Side-hustling entrepreneurs who want to grow their business without quitting their day jobs.
His money making plan: Building a suite of digital products and using Instagram and LinkedIn to attract followers to his email list (just like all the business influencers tell you to).
His dream: Making enough money from his digital products to quit his consulting job and work from anywhere (preferably somewhere with plenty of sunshine and fast wifi).
🆘 The crisis
Sam was getting frustrated with his business progress.
After months of effort, he had created three different digital products but sales were disappointing.
One afternoon at his favorite coffee shop, he noticed someone working on a psychology book and struck up a conversation.
The person introduced himself as Daniel, a successful entrepreneur who works as a business advisor.
Sam told Daniel about his struggles with his digital products.
Razzle-dazzle! exclaimed Daniel, his eyes lighting up like a superhero spotting a villain. I can totally help you understand what's going wrong here!
For the first time in months, Sam felt like maybe his business wasn't doomed after all.
Chapter 1: 🧠 Two thinking systems: Why your brain fights against itself
🔥 The challenge
Sam explained how he kept making impulsive decisions about his business that later seemed obviously wrong.
He couldn't understand why he kept repeating the same mistakes despite knowing better.
Core Problem: Making important business decisions based just on gut feelings
· · ·
🌈 The big idea
Zazzy-wazzy!, You gotta know about Two Thinking Systems, Sam!, hollered Daniel
Our brain has two different thinking systems: a fast, automatic "gut feeling" system and a slow, careful "logical" system.
System 1 is fast, automatic, and emotional while System 2 is slow, deliberate, and logical.
➡️ Before making any big decision, pause and ask yourself: "Am I using my quick gut reaction or my careful thinking here?"
Just like in The Matrix when Neo had to learn to see the code behind reality, you need to recognize which thinking system is controlling your decisions at any moment.
· · ·
🏄 Example
Ramit Sethi, creator of the "I Will Teach You To Be Rich" course, noticed he kept making launch mistakes when rushing.
He implemented a "decision day" where he'd step back from creating content and just think through major product decisions.
His refund rate dropped by 24% on his next launch as he avoided impulsive decisions about pricing and positioning.
His business grew more predictably once he recognized when to use slow, careful thinking for important decisions rather than quick reactions.
· · ·
🎁 The breakthrough
Holy Moly! Sam blurted
He realized he had been letting his System 1 make huge business decisions like pricing and product creation without even knowing it.
He now understood he needed to recognize which decisions required his slower, more logical System 2 thinking to avoid expensive mistakes.
Core Solution: Use careful thinking for important decisions, not just gut reactions
Chapter 2: 😴 Brain Energy Saver: The sneaky shortcuts sabotaging your success
🔥 The challenge
Sam was reflecting on the two thinking systems and had a new question.
If System 2 is more logical and accurate, why don't we use it all the time?
Core Problem: Making key decisions when mentally exhausted
· · ·
🌈 The big idea
You need to understand Brain Energy Saver, Sam!, exclaimed Daniel, adjusting his imaginary cape
Your brain tries to save energy whenever it can.
Slow thinking takes a lot of brain power, so your brain uses fast thinking whenever it can.
➡️ Block out your highest-energy hours each day specifically for making important business decisions.
It's like in Limitless when Eddie realizes his brain pill gives him access to deeper thinking - except you don't need a pill, just awareness of when your brain is taking shortcuts.
· · ·
🏄 Example
Marie Forleo, online business educator, noticed her content quality dropped dramatically in the afternoons.
She restructured her day to work on course creation only during her first 3 hours after coffee, when her mind was sharpest.
Her content completion rate jumped from 35% to 78% and student satisfaction scores increased.
By protecting her peak mental energy for creative work, she produced better courses with less effort and stress.
· · ·
🎁 The breakthrough
Holy Smokes! exclaimed Sam, his eyes widening
He realized he was making his most important business decisions when his brain was already tired and couldn't think deeply.
He committed to planning his product strategy only when his mind was fresh and energized so his System 2 thinking would be at full power.
Core Solution: Schedule important decisions for peak mental energy
Chapter 3: 🏃♂️ Quick decision Machine: Are your brilliant ideas just brain fiction?
🔥 The challenge
Sam was starting to notice his thinking patterns but had a new problem.
He found himself jumping to conclusions about why his products weren't selling without actually having evidence.
Core Problem: Creating products based on assumptions not facts
· · ·
🌈 The big idea
You gotta watch out for your Quick Decision Machine, Sam!, Daniel said while striking a superhero pose
Your brain makes up simple stories from the few facts it has.
Your fast brain skips over missing facts and jumps to conclusions based only on what it sees.
➡️ List what you know AND what you don't know before making business decisions about what your customers want.
It's like in Sherlock Holmes when he says "I never guess. It is a shocking habit—destructive to the logical faculty." Your business needs facts, not stories.
· · ·
🏄 Example
Pat Flynn of Smart Passive Income assumed his audience wanted advanced monetization strategies for their podcasts.
When he surveyed his email list, he discovered most hadn't even started a podcast yet—they were stuck on the technical setup.
He scrapped his planned advanced course and created "Power-Up Podcasting" focusing on the basics of getting started.
The beginner course generated over $400,000 in its first year because he built what his audience actually needed rather than what he assumed they wanted.
· · ·
🎁 The breakthrough
Holy Cow! said Sam, slapping his forehead
He realized he had created products based on what he assumed his audience wanted without any real evidence.
He decided to collect actual data about customer needs before creating his next digital product to ensure people would actually buy it.
Core Solution: Collect evidence before creating products
Chapter 4: 😌 Smooth Thinking: The dangerous reason you believe what you believe
🔥 The challenge
Sam noticed he tended to believe ideas that just "felt right" without questioning them.
He wondered why some business advice seemed more believable than others, regardless of evidence.
Core Problem: Overcomplicating your marketing and making it hard to understand
· · ·
🌈 The big idea
Flippity-zippity!, You're experiencing Smooth Thinking, Sam!, Daniel exclaimed with a dramatic whisper
You automatically believe ideas more when they're simple or you've heard them before.
Things you hear often or are easy to understand feel more true than tricky ideas.
➡️ Simplify your product descriptions and marketing until it feels almost too basic, then use that version.
It's like in Inception when ideas that feel natural are actually planted - sometimes the business ideas that feel "obviously true" are just the ones you've heard most often.
· · ·
🏄 Example
Amy Porterfield initially used complex, jargon-filled language when explaining her digital course academy.
She completely rewrote her sales page using simpler words and shorter sentences a 5th grader could understand.
Her page conversion rate increased from 1.2% to 3.8% with no other changes to the offer.
By simplifying her message, Amy made her course feel more valuable and trustworthy to potential customers who were overwhelmed by technical language.
· · ·
🎁 The breakthrough
Holy Guacamole! Sam said, his jaw dropping
He realized his products weren't selling because his sales pages were too complicated and filled with jargon, creating mental confusion for potential buyers.
He decided to simplify his marketing to make it easier for customers to understand the value, which would increase their trust and make them more likely to buy.
Core Solution: Simplify marketing until it feels too simple
Chapter 5: 🔄 Easy Way Out: The invisible question swap killing your business
🔥 The challenge
Sam was reflecting on his previous learning and noticed a weird pattern.
When trying to figure out complex business problems, he often ended up answering much simpler questions without realizing it.
Core Problem: Answering easier questions without realizing it
· · ·
🌈 The big idea
You've discovered the Easy Way Out, Sam!, Daniel shouted
When faced with hard questions, your brain secretly substitutes easier ones.
You don't even notice when you've switched from the original question to a simpler one.
➡️ Write down the exact question you need to answer before brainstorming solutions.
It's like in Moneyball when scouts thought they were evaluating "Will this player help us win games?" but were actually answering "Does this player look like a good baseball player?" The questions seem similar but lead to completely different decisions.
· · ·
🏄 Example
Teachable founder Ankur Nagpal kept asking himself "How can I improve my course platform?"
This led to endless feature additions that made the platform complicated and expensive to maintain.
When he refocused on the actual question "How can course creators make more sales?" he shifted to improving marketing tools.
Teachable's growth accelerated dramatically when they stopped answering the easier engineering question and tackled the harder marketing question their customers really cared about.
· · ·
🎁 The breakthrough
Holy Bananas! blurted Sam, blinking rapidly
He realized when asking "Will this product sell?" he was actually answering the much easier question "Do I feel excited about this idea?" without noticing the switch.
He committed to focusing on the real questions that matter: "Is there evidence my audience wants this?" and "Will they pay for it?" rather than letting his brain take the easy way out.
Core Solution: Write down the exact question before answering
Chapter 6: 🔮 History Rewriter: The mind trick making you miss million-dollar opportunities
🔥 The challenge
Sam was looking back at his business journey and had a realization.
All his past mistakes seemed obvious now, making him wonder why he couldn't see them coming.
Core Problem: Judging past decisions with present knowledge
· · ·
🌈 The big idea
You've run into the History Rewriter, Sam!, Daniel exclaimed
Your brain makes up simple stories to explain past events.
These stories make past failures look obvious, like you should have seen them coming.
➡️ Keep a decision journal documenting your thinking BEFORE you know the outcome.
It's like in The Sixth Sense where everything seems obvious on second viewing - but only because you already know the twist. Business outcomes feel predictable after they happen, but rarely are beforehand.
· · ·
🏄 Example
Affiliate marketer Michelle Schroeder-Gardner of Making Sense of Cents analyzed why her first course launch failed.
She initially blamed her email list size and spent months growing it before her next launch.
When she reviewed her pre-launch notes, she discovered she had skipped most of her planned warm-up emails.
Her second launch succeeded when she followed a documented launch process rather than creating a false story about why her first launch "obviously" failed.
· · ·
🎁 The breakthrough
Holy Mozzarella! exclaimed Sam, looking upward thoughtfully
He realized he was being too hard on himself for past business "mistakes" that weren't obvious at the time and was creating false stories about how he "should have known better."
He decided to focus on improving his decision process for the future rather than beating himself up about past results that only seemed predictable in hindsight.
Core Solution: Write down both your decisions and reasons in a journal to track what works
Chapter 7: 👨🦯 Mistake Blindness: Why smart people keep making dumb decisions
🔥 The challenge
Sam was getting better at noticing his thinking patterns but faced a new hurdle.
He found himself extremely confident in his new product ideas, despite past failures.
Core Problem: Being too confident without supporting evidence
· · ·
🌈 The big idea
Wibbly-wobbly!, You're suffering from Mistake Blindness, Sam!, Daniel said with a sharp clap
Your brain is naturally overconfident in its judgments and predictions.
We stay sure of ourselves even when we see proof we're wrong.
➡️ Look for problems in your business ideas, then test them with small $50-100 experiments before going all-in.
It's like in Fight Club when the narrator doesn't see his own alter ego - we're blind to our own decision-making flaws until we actively look for them.
· · ·
🏄 Example
Digital marketer Ryan Levesque was completely confident his new quiz funnel course would be a hit.
Before building the entire course, he created a simple $27 mini-course testing the core concepts.
Only 17 people purchased, revealing weak demand despite his strong conviction about the idea.
By testing his idea with a minimal investment first, Ryan saved thousands of dollars and months of effort creating a comprehensive course that wouldn't have sold well.
· · ·
🎁 The breakthrough
Holy Mackerel! Sam said, fist pumping the air
He realized his confidence in his new product ideas wasn't based on evidence but instead on overly optimistic stories he was telling himself.
He decided to create small tests for his ideas before fully committing to them, so he could check his blind confidence against real-world feedback.
Core Solution: Test ideas small-scale before full commitment
Chapter 8: 📊 Expert Followers: The shocking truth about expert advice
🔥 The challenge
Sam was reflecting on how to improve his product creation process.
He wondered whether he should rely on his growing expertise or use more structured approaches.
Core Problem: Relying on inconsistent judgment for repeated decisions
· · ·
🌈 The big idea
Let me tell you about Expert Followers, Sam!, boomed Daniel
Simple formulas consistently outperform expert judgments in predictive tasks.
Human experts are often inconsistent and influenced by irrelevant factors.
➡️ Create simple checklists and scoring systems for recurring business decisions.
It's like in Moneyball when statistical models beat baseball scouts' intuition - the simple formula doesn't get tired, emotional, or distracted by irrelevant factors.
· · ·
🏄 Example
Ebook publisher Steve Scott (S.J. Scott) used to decide which books to write based on his personal interests and hunches.
He created a simple scoring spreadsheet with weighted criteria: keyword search volume, competition level, and monetization potential.
Books selected using his scoring system earned 3.2x more revenue than those chosen by intuition alone.
Steve's simple formula consistently outperformed his expert judgment, even though he had already published over 40 successful books.
· · ·
🎁 The breakthrough
Holy Molasses! exclaimed Sam, his eyes widening
He realized he was making inconsistent decisions about his product features based on his mood and recent experiences rather than using a reliable system.
He decided to create a simple scoring system for evaluating product ideas based on audience need, willingness to pay, and ease of creation instead of relying on his inconsistent judgment.
Core Solution: Create simple decision rules for consistency
Chapter 9: 🔍 Experience Wisdom: The hidden rule for knowing when your instincts are lying
🔥 The challenge
Sam was confused by the seeming contradiction in Daniel's advice.
If human judgment is flawed, are there ever times when he should trust his intuition?
Core Problem: Trusting gut feelings in unpredictable situations
· · ·
🌈 The big idea
Now we need to talk about Experience Wisdom, Sam!, Daniel said
Sometimes your gut feelings can be right, but only under specific conditions.
You can trust your gut only in situations that are predictable and give you fast, clear feedback.
➡️ For market predictions, rely on actual customer data from surveys or small tests rather than your intuition.
It's like in Top Gun where pilots develop reliable instincts - but only after thousands of hours of practice with immediate feedback. Business isn't always like that.
· · ·
🏄 Example
Copywriter Joanna Wiebe trusted her intuition about which headlines would convert best after years of writing copy.
When she began A/B testing headlines, she discovered her intuition was right only about 30% of the time.
However, her intuition about design elements was accurate about 80% of the time due to more consistent feedback in that area.
Joanna now trusts her experience for design decisions but relies strictly on testing data for critical copy elements like headlines and call-to-action buttons.
· · ·
🎁 The breakthrough
Holy Toledo! Sam said, slapping the table enthusiastically
He realized he'd been trusting his gut feelings in areas where he had no real expertise or training, like predicting what his market would want next year.
He decided to rely on data and testing for market predictions while only trusting his experience for production quality where he had developed genuine expertise through practice and feedback.
Core Solution: Trust data over instinct for predictions
Chapter 10: 🌎 Similar Situation Wisdom: The planning secret of billionaire entrepreneurs
🔥 The challenge
Sam was planning the timeline for his new course creation.
He estimated it would take him just two weeks, though his previous courses had all taken much longer.
Core Problem: Believing your project will take much less time than similar ones took others
· · ·
🌈 The big idea
Zoomy-whammy!, You need to adopt the Similar Situation Wisdom, Sam!, Daniel exclaimed while jumping from his chair
We focus on why our situation is special and ignore how long these things typically take.
Looking at what happened with similar projects gives more accurate predictions than detailed analysis of your specific case.
➡️ Research how long similar projects typically take before making your own timeline.
It's like in Freaky Friday when the characters can see others' situations clearly but are blind to their own - sometimes we need outside perspective to see reality.
· · ·
🏄 Example
Course creator Ali Abdaal estimated his new productivity course would take just three weeks to complete.
He researched how long similar course creators took on similar projects and found the average was 2-3 months.
By planning for a 10-week timeline instead, he avoided burnout and delivered a higher-quality product on schedule.
Ali's more realistic timeline, based on others' experiences rather than his own optimism, allowed him to create consistent content without the stress of missed deadlines.
· · ·
🎁 The breakthrough
Holy Cannoli! blurted Sam, his mouth falling open
He realized his two-week estimate was wildly unrealistic because he was focusing on his specific situation (inside view) while ignoring the statistical reality of how long similar projects actually took.
He decided to base his timeline on past examples rather than his optimistic scenario, finally accepting that the outside view of similar situations was more accurate than his personal predictions.
Core Solution: Base estimates on similar past examples
Chapter 11: 🖼️ Same-but-different Effect: The tiny word change that doubled sales
🔥 The challenge
Sam was struggling with how to price his upcoming course.
He couldn't decide between different pricing strategies that seemed to lead to very different outcomes.
Core Problem: Describing your offer in only one way and missing potential customers
· · ·
🌈 The big idea
You need to understand the Same-but-different Effect, Sam!, Daniel exclaimed
The same facts shown in different ways leads to completely different decisions.
The way choices are presented greatly changes what people pick.
➡️ Try selling your product with different angles (saving time vs. making money vs. reducing stress) to see which converts best.
It's like in The Usual Suspects when the same events take on completely different meanings depending on how they're framed - the facts don't change, but your interpretation does.
· · ·
🏄 Example
Online educator Mariah Coz tested two different ways to describe the same freelance writing course.
Version A emphasized "freedom to work from anywhere" with the same content and price.
Version B emphasized "financial security during economic uncertainty" with identical content and price.
During pandemic times, Version B sold 2.4x more courses, proving that the same offer can perform dramatically differently depending on how it's framed.
· · ·
🎁 The breakthrough
Holy Chili Peppers! exclaimed Sam, nodding slowly
He realized he was only presenting his course benefits in one way, missing out on potential customers who might be motivated differently by the same information.
He decided to test both framings—"saving 10 hours per week" and "earning $500 more per month"—to see which resonated more with different segments of his audience.
Core Solution: Test multiple ways of framing your offer
Chapter 12: 🌈 Happiness Illusion: Why your business goals might be making you miserable
🔥 The challenge
Sam was working hard on his business but wondered if success would actually make him happier.
He found himself thinking, "Once I reach $10K per month, then I'll be satisfied."
Core Problem: Sacrificing present happiness for future goals
· · ·
🌈 The big idea
Watch out for the Happiness Illusion, Sam!, Daniel said
We consistently overestimate how much any single factor will affect our long-term happiness.
Even big successes and failures don't affect your happiness as much as you think they will.
➡️ Build a business that brings daily satisfaction, not just a distant payoff.
It's like in The Pursuit of Happyness when the protagonist realizes happiness isn't a destination - you need to find meaning in the journey itself, not just the outcome.
· · ·
🏄 Example
Food blogger Pinch of Yum founder Lindsay Ostrom worked 80-hour weeks pursuing blog traffic milestones.
Despite reaching her traffic goals, she found herself increasingly unhappy and burned out.
She restructured her business to include only the content creation parts she enjoyed and hired help for the rest.
Her business revenue actually increased after she focused on enjoyable daily work rather than just growth metrics, and she regained her passion for food photography and recipe development.
· · ·
🎁 The breakthrough
Holy Ravioli! said Sam, leaning back thoughtfully
He realized he was sacrificing his daily happiness for a future financial goal that might not actually make him any happier when he reached it, due to the focusing illusion.
He decided to reshape his business to include more activities he actually enjoyed rather than just chasing metrics, recognizing that his journey needed to be satisfying, not just the destination.
Core Solution: Build a business you enjoy day-to-day
🏆 The parting
I think this is the last time we'll need to meet, Sam, but let me know how things go, Daniel said with a grin.
Remember, you're like Batman now - you've got awesome tools, but you gotta practice using them in real situations.
You're gonna do amazing things once you get those two thinking systems working together!
Daniel gave Sam an enthusiastic high-five, then pretended to disappear behind an invisible smoke bomb.
🎉 The happy ending
Six months later, Sam had launched two new digital products that were significantly more successful than his previous attempts.
His previous courses had made less than $1,000 each, but his new offerings were consistently generating $15,000+ per month.
Instead of working 60-hour weeks, he was now able to take Fridays off and had finally booked that trip to Bali he'd been dreaming about.
🧘♀️ The simple success recipe
The key lessons that transformed the business:
Recognize which thinking system you're using - Your fast, intuitive System 1 is great for some tasks but terrible for others. Knowing which system to use when will save you from those epic facepalm moments that haunt solopreneurs at 3 AM!
Question your overconfidence - When you're absolutely certain about a business decision, that's exactly when you should slow down and look for contrary evidence.
Create simple decision rules - When you make the same type of decision over and over, don't just rely on how you feel each time. Instead, create a simple yes/no checklist that you can use every time. These checklists almost always work better than just going with what feels right.
Look for the outside view - Before planning your next project, look at how long similar projects typically take other people. Your optimistic timeline is probably way off!
Test different frames - How you present your offers dramatically affects whether people buy. Always test multiple ways of framing the same product.
✨ Loosely inspired by...
Sam Ovens, a business coach who helps consultants build profitable businesses.
He gained a massive following by focusing on straightforward, no-nonsense advice for getting clients and building systems.
His consulting accelerator program has helped over 20,000 people start and grow consulting businesses.
🥂 Your turn!
That's it, my fellow rebels!
Now you understand the two thinking systems running your business decisions. When you're pricing your next digital product or deciding which course to create, you'll know when to trust your gut and when to slow down and analyze.
As Kahneman says, "The way to block errors that originate in System 1 is simple in principle: recognize the signs that you are in a cognitive minefield, slow down, and ask for reinforcement from System 2."
Today, start by keeping a decision journal - write down the reasoning behind one important business decision before you make it.
Your brain wants to take shortcuts, but now you have the tools to recognize when those shortcuts lead you astray!
Like Thor learning to control his lightning powers, you now can harness both your thinking systems to create the business you've been dreaming of!
