Worrying and decision making
I have a theory that there is a causal relationship between people who cannot distinguish between a good decision and a good outcome, and people who worry too much about things they have no control over.
For example: you train your kid to drive a car. After years of training and supervision, you decide that your kid is ready to drive on their own for the first time. They do that and get into a car accident.
Did you make a good decision to let them drive on their own?
If you’re the kind of person who says “no, it was a bad decision”, you probably worry unnecessarily. A good decision doesn’t require a good outcome to be good, just a good process of getting there. Even though the outcome is bad, it was still the right thing to do. Many people literally cannot separate the two.
