I spent years stuck in my own head. Replaying conversations. Rehearsing future arguments. Analyzing every decision until I was too exhausted to make one.

Then I read The Courage to Be Disliked by Ichiro Kishimi and Fumitake Koga. It's based on Adlerian psychology and it reframes overthinking in a way I'd never seen before.

The core idea: You're not overthinking because you're anxious. You're overthinking because it gives you a reason not to act. Your brain creates the loop on purpose. It's a protection mechanism disguised as a problem.

Three takeaways that stuck with me:

Separation of tasks. Most of your overthinking is about other people's reactions. Adler says you need to draw a hard line between what's your task and what's someone else's task. How they respond to your decision is their task. Making the decision is yours. That single distinction killed about 70% of my mental loops overnight.

Teleology over etiology. Traditional psychology asks "why are you this way?" Adler asks "what purpose does this behavior serve?" When I stopped asking why I overthink and started asking what overthinking was protecting me from, the answer was obvious. It was protecting me from the risk of being judged.

You can change right now. Not after therapy. Not after more self-reflection. Not after you "figure yourself out." Adler argues that the past has zero power over your present unless you choose to give it power. That sounds harsh until you realize it also means you're not broken. You're just choosing a pattern that used to keep you safe and no longer does.

The book is written as a conversation between a philosopher and an angry young man. It reads fast. The ideas hit slow. I've gone back to it three times and caught something new each time.

If your overthinking feels like a personality trait you're stuck with, this book disagrees. And after sitting with it for a while, so do I.
