Normally, I spend a week on the outline and take two weeks to write the book.

People always ask, 'How do you write so many books?' And I say, I work a lot. I work six or seven days a week.

So many people in their 20s and 30s, on Twitter, say 'Please write something for us,' so I have to listen to them, they're my audience.

Well, when I was 13, for my bar mitzvah I received my first typewriter. And that was special.

When I write, I try to think back to what I was afraid of or what was scary to me, and try to put those feelings into books.

Believe it or not, my introduction to scary literature was 'Pinocchio.' My mother read it to me every day before naptime when I was three or four. The original 'Pinocchio' is terrifying.

I feel that good fantasy will always be in demand. I think children especially need literature that helps them escape from the real world, which is very scary to them right now.

I got the chance to do things that I dreamed of when I was a kid: I got to travel around the world; I had my own 'Goosebumps' attraction at Disney World; I've been on TV and had three TV series.

I read everywhere. I read every day. I read on the couch with my dog in the afternoon and at night. I try to read at least two to three hours a day. I read only fiction.

I really wanted to be a cartoonist, and I was in 4th or 5th grade and I would bring my drawings in, and I'd look around, and everyone could draw better than me. Everyone. My drawings were just awful. So that's why I had to write.

I set a goal for myself everyday when I write - 10 pages a day - and it's much harder because I'm too dumb to turn off my Twitter and everything so it's always on and it's a real distraction. It's a major distraction.

I started writing when I was 9 years old. I was like this weird kid who would just stay in my room, typing little funny magazines and drawing comic strips.

If you want to be a writer, don't worry so much about writing. Read as much as you can. Read as many different writers as you can. Soak up the styles.

It's hard for children's authors to be accepted when they try to write adult books. J.K. Rowling is the exception because people are so eager to read anything by her, but it took Judy Blume three or four tries before she had a success.

It's my job, too, to keep up with pop culture and what the kids are into 'cause you don't want to sound like an old man trying to write for kids. I spend a lot of my time spying on them.

Most fears are basic: fear of the dark, fear of going down in the basement, fear of weird sounds, fear that somebody is waiting for you in your closet. Those kinds of things stay with you no matter what age.

Twitter is fun because it lets me stay in touch with all my original readers who grew up with my books. I love hearing from readers instantly on Twitter.

When I was a kid, there were these great comic books called 'Tales From The Crypt' and 'The Vault of Horror.' They were gruesome. I discovered them in the barbershop and thought they were fabulous.

When I write for kids, I have to make sure they know what can't happen. They have to know it's a fantasy. But when I write for adults, they have to think it's real. Every detail has to be real or they won't buy it.

I used to get a haircut every Saturday so I would never miss any of the comic books. I had practically no hair when I was a kid!
