Perfectionist is sometimes the wrong word... It means like you're never satisfied, or you're upset by every single failure - any type of failure. And so for me, I don't look at failure as necessarily a bad thing as long as I'm able to learn from it and take something from it, so that next time I'm in that situation I know how to succeed.
A lot of times, I've always looked at pitching in the All-Star Game as a prelude to how you pitch in the postseason, sometimes how you might have to pitch on two days' rest out of the pen, only throw one inning and then you have to go face the best hitters. That's what you do in the All-Star Game.
