I'm surprised at some stuff I know but don't know I know until I'm talking to someone, or more often, emailing and commenting on blogs.
The latest is this: having dogged faith in your aesthetics and process and technique results in good art.
You know how we're always supposed to listen to criticisms, particularly ones we don't agree with straight away. I went to a convent school and had conservative (where child-rearing is concerned), so I was lucky to have criticisms galore. Even when grownups thought they were disguising them as encouragements. And I try to listen, though I find with my work, sometimes I need to shut them out, because I am a) too easily influenced and distracted, and b) haven't learned how to listen, consider and then ignore.
I learned yesterday that I knew artist friends I admire have faith in themselves, and make the "coming from within them" stuff. I don't know if they consider criticisms; at least one never does.
Sometimes it's gotta be good to be insular.
