So, Neil Gaiman said this in an interview about ten years ago:
I was always so relieved that anyone wants to publish anything I’ve written. In many ways I feel like the biggest challenge hasn’t come yet. Because, if pressed, I would confess that what I’m really scared of is that one day somebody will knock at the door and they’ll have a clipboard. They’ll say, “Mr. Gaiman?” And I’ll say “Yes.” They’ll say, “It says here that you get to make stuff up and get paid for it.” I’ll say, “Yes.” “And it says here that you can do anything you want. You can go and do fantasy and you can do real fiction and you can do TV, films, whatever you want.” And I’ll say, “Yes.” And they say, “Well it’s over. It’s done. We’ve caught up with your game, Sir. You are going to have to go and get a real job. And work normal hours.”
Yes, Mr. Croup and Mr. Vandemar show up and they say “It’s over. You are now going to have to get a real job.” I will have gone to that point, seemingly expecting that this writing thing would go on for ages. I’d then think, “Well, it’s a fair cop.” I would go off and have to get a real job and get up the morning and wear a suit. I suppose I’d secretly make some things up in my head for myself before I went to bed at night, or before I go to sleep anyway lying in bed, sort of making up little stories. But I’d never be able to tell anybody. That’s the thing I’m scared of.
I mean, I know these fears are fairly universal, but it’s somehow comforting to see someone like Neil articulate them.

Oh, and go read the Graveyard Book. It’s wonderful.
