That attitude will freeze you right away. Business is what people do. Sometimes they do it with other people and sometimes they do it to other people. Unfortunately, no one knows what they are. Writing, I think, is not apart from living.
Writing is a kind of double living.
The writer experiences everything twice. Once in reality and once in the mirror which waits always before or behind. Writing has laws of perspective, of light and shade just as painting does, or music. If you are born knowing them, fine. If not, learn them.
