I refocus my enjoyment to learning the game instead of winning. Like, I'm in a tournament thinking things like , "oh cool, this is a tough spot. It will be interesting to analyze it later" and the such. It's very different from where I was agonizing over winning flips. Don't get me wrong, I still want to punch something if I bust with AA allin preflop vs an underpair, but having something to look forward to beyond the result of a hand, makes it a different experience.
