Henry Miller once wrote down his rules or “commandments” as he said about his writing schedule. Here they are:
1. Work on one thing at a time until finished.
2. Start no more new books, add no more new material to “Black Spring.”
3. Don’t be nervous. Work calmly, joyously, recklessly on whatever is in hand.
4. Work according to Program and not according to mood. Stop at the appointed time!
5. When you can’t create you can work.
6. Cement a little every day, rather than add new fertilizers.
7. Keep human! See people, go places, drink if you feel like it.
8. Don’t be a draught-horse! Work with pleasure only.
9. Discard the Program when you feel like it—but go back to it next day. Concentrate. Narrow down. Exclude.
10. Forget the books you want to write. Think only of the book you are writing.
11. Write first and always. Painting, music, friends, cinema, all these come afterwards.
Fairly great stuff from a brilliant writer. He like many others wrote a book about writing called Henry Miller on Writing you can get this widely on the internet and on amazon.
