Art is serious business but the painter's life doesn't have to turn you into a curmudgeon.
I suggest if you want to survive in this business - have a sense of wonder, humility and humor in everything you do!
Believe me, no one is interested in your artistic woes or angst. It's your CREATIVITY that stops people in their tracks.
