I think the best advice I give is to try not to write. Try not to overwrite, try not to make it sound too good. Just use your own voice. Use your own style of putting it down.
Everyone has his own sound. I'm not going to presume how to tell anybody how to write.
My most important rule is one that sums up the 10: If it sounds like writing, I rewrite it.
It doesn't have to make sense, it just has to sound like it does.
If it sounds like writing, I rewrite it.
