Negative thinking and creativity

"We seldom accept negative comments from others, however, we so often accept our own inner negative chatter."

This is a quote I saw today on a site called the daily om. I think it is a good one for artists, writers and musicians. It is so easy to let our negative thoughts sabotage our work. It is not good enough, I can improve on it, it won't sell, a new style may fail....there is so much we tell ourselves. We would bristle up if a critic or patron said this to us. We must be our own best friends, and nurture our own creative selves.
