Whatever it is—whatever it is, do it! Sure there are going to be mistakes. Everything’s not going to be perfect. I’ve written thousands of words that no one will ever see. I had to write them in order to get rid of them. But then I’ve written a lot of other stuff too. So the good stuff stays, and the old stuff goes.
