There are two kinds of writer: those that make you think, and those that make you wonder.
It is comparatively easy to become a writer; staying a writer, resisting formulaic work, generating ones own creativity - thats a much tougher matter.
A writer should say to himself, not, How can I get more money?, but How can I reach more readers (without lowering standards)?
Writers must fortify themselves with pride and egotism as best they can. The process is analogous to using sandbags and loose timbers to protect a house against flood. Writers are vulnerable creatures like anyone else. For what do they have in reality? Not sandbags, not timbers. Just a flimsy reputation and a name.
