Whatever I do will be wrong, so why bother putting effort into it and getting myself all upset when I find out (surprise surprise!) it's wrong?
I really hate computer animation. It is just completely illogical, and all the while, I think, "If this were stop motion, I wouldn't have to worry about the character doing screwy things when I animate. And no, I didn't finish last night. Something about nothing working makes me believe it's time for a break.
