If your not happy with the idea, that its hard to sell paintings, it’s not being an artist that bothers you, it’s the act of painting and selling paintings, that you have a problem with. You have artists in banking and marketing, because it’s not important what you create, it is the act of creation and the joy and pleasure that it brings. Maybe it’s time to stop pondering about why and to start figuring out how. And mind you, this is not the motivational why; it’s impossibly important to know why we do what we do, but the universal why. The one you don’t have to like, only understand.
