Good decisions come from good processes, not from moods. Under pressure, the mind grabs simple stories and ignores second-order effects.
I learned to slow down and map cause-and-effect. What must be true for this to work? What are the biggest risks? What are the likely consequences beyond the first one? Clear questions beat clever answers.
Decision making improves when you use the right inputs. Seek disagreement, then evaluate arguments by the track records and reasoning quality of the people making them. Treat believability as a weight, not a rank.
Finally, write decisions down and review them later. The review turns outcomes into feedback on your thinking. Over time, you build a library of patterns—what you misjudge, where you overreact, and which conditions predict success. That is how judgment is trained.
