Love. Fall in love and stay in love. Write only what you love, and love what you write. The key word is love. You have to get up in the morning and write something you love, something to live for.
The answer to all writing, to any career for that matter, is love.
Why go to a machine when you could go to a human being?
You can't learn to write in college. It's a very bad place for writers because the teachers always think they know more than you do - and they don't. They have prejudices. They may like Henry James, but what if you don't want to write like Henry James? They may like John Irving, for instance, who's the bore of all time.
