These ten tips from Richard Ford. He won the Pullitzer Prize for his novel Independence Day (not the one with Will Smith and Jeff Goldblum in it, a different one).
1 Marry somebody you love and who thinks you being a writer's a good idea.
2 Don't have children.
3 Don't read your reviews.
4 Don't write reviews. (Your judgment's always tainted.)
5 Don't have arguments with your wife in the morning, or late at night.
6 Don't drink and write at the same time.
7 Don't write letters to the editor. (No one cares.)
8 Don't wish ill on your colleagues.
9 Try to think of others' good luck as encouragement to yourself.
10 Don't take any shit if you can possibly help it.
