I really like this quote by Elizabeth Gilbert who wrote EAT PRAY LOVE. I lifted the quote right off Valerie Ipson's post from today (I like her t-shirt. I think a certain writing group should make and sell them)(just sayin').
"One day, when I was agonizing over how utterly bad my writing felt, I realized: "That's actually not my problem." The point I realized was this-I never promised the universe that I would write brilliantly; I only promised the universe that I would write. So I put my head down and sweated through it, as per my vows."
