I like the quote that says "art is the lie that reveals the truth."
I saw a sculpture in a gallery of a crouching man. It was crudely constructed of newspaper and duct tape, but it was more memorable than any bronze sculptures I have ever seen. You felt the power in the thing, that at any moment that man was going to stand up and do something.
I know enough about the creative process to know that being afraid (of not reaching perfection, or of people not liking it, of people will think you are stupid, etc) will keep you from doing your best work. When you let that go, when you accept that you are deeply flawed (as we all are) then you can start to have something.
