Some short takeaways from the book Thinking in bets by Annie Duke:

Would your belief in something stand up to the question, “Wanna bet?” If you had to gamble significant money on that belief, would you still feel 100% about it? Or maybe more honestly 60%?

When a decision doesn’t work out, don't treat that result as if it were an inevitable consequence rather than a probabilistic one. Don't focus only on the poor outcome.

A great decision is the result of a good process - not that it has a great outcome.
