Constantly :P And then I get angry because I feel entitled and yet I also feel like I'm not getting what I want. But as long as we feel entitled and uptight about it, I guess we don't allow much room for being actually happy...
I've had plenty of times where I thought I was the luckiest person on earth, and that things were actually balancing out with all the horrible crap from the past. Like when I first flew, like when I went parachuting. But those moments pass, you lose the euphoric feeling, and then you feel entitled again. Never ending mental spiral.
I guess when we live through really nice moments, we have to make sure we don't forget them. It's okay to forget them for a while, but we have to make sure to remember them at some point when we're in rock bottom. Because if we remember those things, we'll also remember that good things do come.
