The Guardian has advice from 14 authors about how to write. My favorite is Roddy Doyle’s:
Do not place a photograph of your favourite author on your desk, especially if the author is one of the famous ones who committed suicide.
Helen Dunmore’s “A problem with a piece of writing often clarifies itself if you go for a long walk” is also sound.
But Richard Ford’s “Marry somebody you love and who thinks you being a writer’s a good idea” takes the cake.
