For a professional writer in the Soviet Union, it works this way. First, you have to have something to say - that's the main thing. Second, it's a matter of who publishes you. If your book has real stuff in it, readers will ferret it out, even in a Siberian journal.
I'm not like a professional writer with professional skills. Songs kind of come into my head the same way they did when I was a kid. I say I'm an overgrown kindergarten kid. I work on songs.
I actually started trying to be a professional writer with novels, and I wrote two that exist and are around... kind of. But they never really went anyplace in particular. I still like them both. What it showed me was that you can spend years on a novel, and then it could just be, like, OK, you spent that time and that's that.
My personal opinion is that, if you're a professional writer, that you do have quotas. So every day I do try to write 800-1,200 words. I don't always achieve it, and the reality is that a lot of the words I write will end up on the cutting-room floor.
If you want to be a professional writer then you need to write consistently. Inspiration strikes about once every blue moon which, for me, is once every two and a half to three months, which is when I'll get really and truly inspired about something.
I've had menial jobs, and 'professional writer' isn't one of them.
I'm not the most talented writer in the world. I know that. But I also know that I'm disciplined, that I work my butt off, and that I make myself write as much as I can. Writer's block is a luxury I can't afford. I'm a professional writer, which means that I put my butt in the chair each day, and I write. Simple as that.
I've been a professional writer for 20 years, and there are contours in that time, crescents and troughs.
One of the ironies of being a professional writer is that, if you are even moderately successful, the very traits that let you succeed as a writer are not much help when the time comes to head out as 'The Author.'
Don't let anyone discourage you from writing. If you become a professional writer, there are plenty of editors, reviewers, critics, and book buyers to do that.
