Much of it is damn good. Certain parts are brilliant. This is my favorite right now:
Give yourself permission to suck. Whenever I read about a writer who produces "clean first drafts" I think Good for you. Now shut up. Which is not to say that I think producing clean first drafts is bad. If you have that skill, wonderful.
But too many prospective writers give up because they feel their first efforts are not good enough. If you can't write clean first drafts, at least write a first draft. You can always fix it later. But if you let your internal editor stop you before you even start, you'll never get anything done.
Bill is one smart guy. Can write a little too.
