Most serious artists I know paint several times a week. Some paint everyday. If you want to become good at anything you do, then you have to work at it. Great hockey players drag themselves to the arenas during the early hours of a day, musicians practice their scales constantly and painters refine their skills most days of the week.
They challenge themselves by capturing subjects that are outside their normal realm. Choose a creative goal and work at it. Don’t be satisfied with being pretty good at something, draw out your best efforts. Show the world your artistic side.
