Much of the activity we think of as writing is, actually, getting ready to write.
Who wanted to creep along in comfort when there was one chance in a thousand of flying?
I believe that with enough practice and good faith, you can learn to recognize when the work is achieved.
One is taught by experience to put a premium on those few people who can appreciate you for what you are.
During the act of writing I have told myself something that I didn't know I knew.
The best antidote I have found is to yearn for something. As long as you yearn, you can't congeal: There is a forward motion to yearning.
