That's certainly true, but I would argue that there's some things that really don't warrant wasting your time / energy with (like you said, mainly inter-personal and superficial stuff like appearances, money, etc.) and others that you should listen to if it's something that continues to bother you.

Weather is a good example: If you find yourself constantly annoyed at the weather and it's possible for you to do so, why not go to somewhere with a climate that might better suit you?

I guess my point is, I agree, it's not worth it getting constantly worked up over stuff, but also one shouldn't ignore one's feelings towards certain things for a prolonged time.
