Don't be a writer, it's a terrible way to live your life, there's nothing to be gained from it but poverty and obscurity and solitude. So if you have a taste for all those things, which means that you really are burning to do it, then go ahead and do it.
I guess the important thing for young writers is to read.
While I was writing poems, I would often divert myself by reading detective novels, I liked them. And there was a period when I read many of them. I absorbed the form, and I liked it, it was a good one, mostly the hard-boiled school, you know, Chandler, Hammett, and their heirs. That was the direction that interested me most.
