I think this is where it’s important to know yourself.
If you’re having a constant stream of anxiety inducing thoughts and light paranoia, learning how to silence those and introduce a more objective view is helpful.
It can be taken too far, though. I had a friend whose company was showing all of the warning signs of financial problems, yet he was on a positivity kick and chose to substitute an “everything works out eventually” mentality. Instead, he rode the company right into their inevitable shutdown and missed some good opportunities to take other jobs along the way because he thought ignoring his gut was the right thing to do.
