I use to rage quit when me and a buddy would go head to head on street fighter alpha 3, I played that dang game 20hours a week and he still would wipe the floor with me. I threw a controller once. heck I could wear out a d-pad in a month LOL but besides that I am not a competitive person so things do not normaly get to me.
But I can understand you and your artwork. its a shame though I bet the stuff you dont like about a project would still blow peoples minds.. When I worked at a copy center and do projects for people I always pointed out things I was not happy with the job. But I had to learn not to do that. We are our worst critics.
hope you get to feeling better!!! and have a good night @saywha !!
