I started off like everyone else does, slogging but having a compulsion to put words on paper. I didn't write or read horror or fantasy, other than children's fantasy, until I was in my teens.
People are famous for being famous and for nothing else. And good luck to them, because it lasts about a year and then they're nothing again.
I used to play football for Real Madrid, and to be on stage for two hours, I can tell you it takes the same amount of strength.
