I don’t think the shortage of artists has much to do with the innate ability to create or initiate. I think it has to do with believing that it’s possible and acceptable for you to do it. We’ve had these doors open wide for only a decade or so, and most people have been brainwashed into believing that their job is to copyedit the world, not to design it.
Stick to your dreams and determine that you're going to make them come true.
