I really don't think life is about the I-could-have-beens. Life is only about the I-tried-to-do. I don't mind the failure but I can't imagine that I'd forgive myself if I didn't try.
I have an almost complete disregard of precedent, and a faith in the possibility of something better. It irritates me to be told how things have always been done. I defy the tyranny of precedent. I go for anything new that might improve the past.
