Many a serious thinker has been produced in prisons, where we have nothing to do but think.

I'm okay for things like theater and stuff but for film, I just didn't think in the right way and I didn't like the business. So I was unhappy. So I was in something that was moderately related to my, what I call my calling or my life's path, which is writing, but it wasn't like the right fit.

It's fortunately a kind of society we live in where we can be diverse. People can take different paths and not feel like they're doing something wrong.

People who are reading my books, or who are thinking about it, have some general idea about the concept of strategy. They're better off than somebody that has none. So I would never say it's useless.
