Minds That Changed Everything
The Undoing Project: A Friendship That Changed Our Minds
by Michael Lewis
Biography/Psychology/Economics
TL;DR
This book isn't about some epic quest; it's about two brainy bros who figured out why we're all walking, talking bundles of bad decisions. They exposed how our minds take lazy shortcuts (heuristics), leading to predictable screw-ups (biases). You'll learn why losing money feels worse than winning it (prospect theory) and how the way information is presented totally messes with your head (framing effects). Basically, it's a masterclass in understanding your own brain's glitches so you can stop being such a simp for your own irrationality and maybe, just maybe, make smarter moves in life, love, and your bank account.
Action Items
Before you hit 'add to cart' on that 'limited time offer' or retweet that wild take, pause for 5 seconds. Ask yourself: 'Am I just being lazy, or is this actually smart?'
Got something you're clinging to that's clearly dead weight (like that old phone with a cracked screen or a 'situationship' that's going nowhere)? Ditch it. The pain of letting go is temporary, the freedom is forever.
Next time someone tries to sell you something (a product, an idea, a 'great' plan for Friday night), flip the script. Ask yourself: 'How would this sound if they said the exact opposite, or framed it in the worst possible light?' See if it still slaps.

Key Chapter
Chapter - Your Brain's Glitchy Shortcuts: Why We're All a Bit Dumb
Okay, so imagine your brain is like that one friend who always takes the 'scenic route' but ends up in a ditch. This chapter dives deep into how our minds use mental shortcuts, or 'heuristics,' to make quick decisions. Sounds efficient, right? Nah, fam. These shortcuts often lead to predictable, facepalm-worthy errors, aka cognitive biases. It's why you might trust a random TikTok 'expert' over actual research, or why you're convinced you're a better driver than everyone else. Understanding these glitches is key to not getting played by your own grey matter. It's about realizing your brain isn't always your bestie, and sometimes, it's just trying to save energy, even if it means making you look like a clown.
Key Methods and Approaches
Your Brain's Lazy AF Shortcuts
(AKA: Heuristics & Cognitive Biases)
Description:
Our brains use quick, dirty mental rules that often lead to predictable, dumb mistakes.
Explanation:
Think of your brain like a cheap GPS that always picks the shortest route, even if it's a dirt road through a swamp. It's trying to save battery (mental effort), but sometimes it just gets you stuck. These shortcuts are why you jump to conclusions or believe something just because it feels right, even when it's total cap. It's like your brain's default setting is 'vibes over facts.'
Examples:
Buying something because it's 'on sale' even if you don't need it, just because the discount feels like a win.
Judging someone's entire personality based on their first text message.
Believing a conspiracy theory because it's simple and fits your existing worldview, even with zero evidence.
Overestimating your chances of winning the lottery because you saw one person win big.
