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.
I have friends that are much better actors than I am that had to quit the business because they couldn't survive the auditions or the rejections, or people just didn't realize how good they were.
