Its funny you ask this, Ive been thinking about the same thing lately. I think, maybe, lots of artistc people, not just writeres but musicians, actors, comedians whatever, result from some sort of hardship. It seems alot of writing(obviouslly not all of it) is either a way of expressing or running away from something. Drinking and drugs are commonly used for that too. Not that I ever drink....Im just guessing....
