"A picture is not about a subject, the subject is merely an impetus to give voice to the problem or experiment the artist selected to be solved, the personal challenge."-- Skip WhitcombPause to think what attracts you to what you've decided to paint. The challenge of the composition or perspective? The color mixing? The difference to what you last painted? The desire to get what wasn't as you'd visualized it last time? Creative problem solving, aka painting.
