When setting goals, make sure you understand the parts of the process you control and the parts that you don’t.
Say your goal is to have good health.
The parts you control are your eating habits, the amount of exercise you do, how you take care of your mental health, etc.
You don't control your genetics and you have limited control over your environment.
Understanding the parts you control and the parts you don't will help you spend your energy on the things that matter.
It doesn’t make sense to worry about your health.
It makes sense to understand the things you can do — and then do them.
It’s not certain that you will have good health because it’s not fully under your control.
But there’s no reason to worry when you’ve done your part.
This is the best way to optimize the probability of getting what you want.
