The ideal is to give up on timewasting/unimportant activities(Quadrants 3&4 on Eisenhower Matrix) and try/begin important activities(Q1&2).
It is incredibly challenging, to accept uncertainty & to do what you are SURE is important & will result in a positive outcome.
If I run for 30 minutes every day then I KNOW that it is beneficial to my health. I am certain. My OCD will ruin it by suggesting that I could breathe polluted air, et cetera. By that suggestion alone, I will not run.
It's a strange dysfunction of your brains executive/decision ability. I value what I am not certain of MORE than what I am certain of.
It is my goal to reverse that logic & when your brain is working against you, it feels as if you're swimming against a current.
