What's One Lesson From A Book That Changed The Way You Make Decisions?

Books shape us in subtle ways. We rarely remember every chapter or every page, but sometimes a single idea from a single book quietly rewires how we think for the rest of our lives.
For some readers, it was learning about the sunk cost fallacy from a behavioral economics book. They suddenly realized why they kept finishing movies they hated, staying in jobs they outgrew, and continuing projects that should have been abandoned. Others learned about delayed gratification from a psychology book and started making different financial choices almost overnight. Some readers picked up the idea of "begin with the end in mind" from a self-help classic and never planned a goal the same way again.
For me, the lesson came from a book about decision-making, and the idea was deceptively simple. Most poor decisions are not caused by lack of intelligence. They are caused by lack of time, calm, and reflection.
The author argued that humans tend to make their worst decisions when they're tired, emotional, or rushed. The solution isn't to think harder. The solution is to design your life so that important decisions are made in calmer states whenever possible. Sleep on big choices. Walk before tough conversations. Avoid major financial moves while exhausted. None of this is glamorous, but it consistently leads to better outcomes than relying on willpower in the heat of the moment.
This connects to a wider concept in psychology called the dual-process theory, popularized by Daniel Kahneman in his book "Thinking, Fast and Slow." Kahneman explained that our minds use two systems. System One is fast, automatic, and intuitive. System Two is slow, deliberate, and thoughtful. Most everyday choices are made by System One, which works fine for routine matters but tends to fail badly when applied to complex or emotional decisions. Knowing when to slow down and engage System Two is one of the most important life skills you can learn, even though it's almost never taught in school.
So I want to hear your story:
