You wanna be the next Tolkien? Don't read big, tolkien-esque fantasies. TOLKIEN didn't read big, tolkien-esque fantasies. He read books on finnish philology. You go and read outside your comfort zone, go and learn stuff. And then the most important thing, once you get any level of quality--get to the point where you wanna write, and you can write--is tell YOUR story. Don't tell a story anyone else can tell. Because you always start out with other people's voices... There will always be people who are better or smarter than you. There are people who are better writers than me, who plot better than I do, but there is no one who can tell a Neil Gaiman story like I can.
The only thing you should have to do is find work you love to do. And I can't imagine living without having loved a person. A man, in my case. It could be a woman, but whatever. I think, what I always tell kids when they get out of class and ask, 'What should I do now?' I always say, 'Keep a low overhead. You're not going to make a lot of money.' And the next thing I say: 'Don't live with a person who doesn't respect your work.' That's the most important thing—that's more important than the money thing. I think those two things are very valuable pieces of information.
