Let your mind follow your heart and let your heart follow your eye and let your brush record it all tenderly.
If ever I go to a figure drawing session and find myself thinking, "Oh man! This model doesn't know how to pose!" or, "Not a good look. We need better looking models." That's when I know that I'm not paying attention. When I start like that it will ALWAYS be a bad drawing day. So I make a point now of thinking always, "I'm gonna do the best I can with what I've got." I draw better that way and often find myself surprised by the result.
