I have no stamina for writing. I stop as soon as a thought is half-formed. Once I only saw in other people's success my own failure. But I don't feel the need to compare myself to someone today. A certain degree of acceptance goes a long way. I was the way I was, I am the way I am, though I believe I can change. It's a practice, like many in my life (prayer, meditation, yogurt.)
"I had hardly begun to read
I asked how can you ever be sure
that what you write is really
any good at all and he said you can't
you can't you can never be sure
you die without knowing
whether anything you wrote was any good
if you have to be sure don't write"
