There is an exercise I teach at colleges: Get yourself a canvas and a bunch of acrylics and go into a very dimly lighted room. Dip a brush into one of the colors, slap it on the canvas, don't look, close your eyes, make a painting, don't look, turn the lights on and see what you've got. I think this releases people from the editor in their life that's always standing over their shoulder saying, "Oh, you don't have any talent; who do you think you are?"
