I once accepted a job I knew was wrong for me. Not suspected — knew. The interview felt off. The manager said things that should have been red flags. The salary was good, and I was tired of looking, and some part of my brain whispered, “Just take it.”
Three miserable months later, sitting in a cubicle that smelled like carpet cleaner and regret, I wondered: what process did I follow? Honest answer: none. I made a life decision on a cocktail of fatigue, hope, and impatience.
Bad decisions rarely come from stupidity. They come from bad process. And process can be improved.
Why Your Brain Is Terrible at Decisions
Your brain was optimized for a world that no longer exists. Small tribes, immediate threats, scarce resources — fast decisions based on incomplete information. Modern decisions are complex, multi-variable, with delayed consequences. Your brain solves them with hardware designed to outrun a lion.
The result: we default to emotion and shortcuts when we need structure and patience.
The Decision Environment
Most advice focuses on the decision itself. The more important question: in what state am I making this decision?
- Fatigue. Decision fatigue is real. Your prefrontal cortex runs out of glucose. Never make important decisions at the end of a long day.
- Emotional arousal. Any strong emotion hijacks rational processing. If your heart rate is elevated, your judgment is compromised. Wait.
- Time pressure. Most “urgent” decisions aren’t actually urgent. Someone else’s deadline is not your emergency.
- Social pressure. Making decisions to please someone changes the calculus in ways you don’t notice.
The 10-10-10 Framework
Before any choice, ask: How will I feel about this in 10 minutes? 10 months? 10 years?
Most bad decisions feel great at 10 minutes and terrible at 10 months. Quitting in a rage. Sending that text. Most good decisions feel uncomfortable at 10 minutes but obvious at 10 years. The hard conversation. Leaving the bad relationship. Short-term pain, long-term alignment.
The Reversibility Test
For reversible decisions (trying a restaurant, starting a side project): decide fast. The cost of a wrong choice is low. Stop overthinking.
For irreversible decisions (signing a lease, moving countries): slow down dramatically. Get information. Sleep on it — literally. Your brain processes complex decisions during sleep in ways your conscious mind cannot.
The Pre-Mortem
Before a big decision, assume it failed spectacularly. Six months from now, this went wrong. Why? What did you miss? What warnings did you ignore?
This surfaces risks your optimistic brain is filtering out. It forces you to consider failure modes that enthusiasm obscures.
After the Decision
The quality of a decision is often determined not by the choice but by what you do after. Commit. Execute. Stop second-guessing. The person who makes a B+ decision and executes fully almost always outperforms the person who makes an A+ decision and hedges it into irrelevance.Bad decisions are inevitable. The goal isn’t perfection. It’s building a system that’s better than your default, so bad decisions become rarer and good ones more frequent. Over a lifetime, that compound advantage is enormous
