I've done a lot of things in a business where you're lucky to stay alive, so when the time comes, I'll be happy to pass my knowledge along and help someone else.
I love the idea of leaving some of the original abstract thought in, because the problem is that when you pick up a pen you become a snob, your own worse critic. You edit yourself in a way that is non-creative.
Actually, I think it's quite sensible not to take yourself too seriously.
