Mine is to not freak out over small things anymore but try not only to weigh the situation logically, but if I feel like I'm in a catch 22 (which could entirely be a product of my own mind) to just simply take the option that gives me the most peace. I try to be definite in my decisions but I've noticed that once I make a decision in peace, often about like 10 minutes later I'll have more clarity to then allow things to progress. As in, I am allowed to change my mind. I don't set hard and fast rules like if I make a decision I have to stick to it at all costs - that would only stress me out. Taking away that pressure has helped me a LOT. I've slipped up, but am always trying and so far things have been pretty good :)
Dude, meditation could be of great service to you.
