If you ever struck it rich, would you give up the day job and concentrate on being a novelist?
Probably not. Where would I get my inspiration? Besides, the routine of the working day keeps me from going insane. When you're young, you resent it; then it becomes a part of you; finally, it's part of what keeps you going. Sad in a way, but that's life. Luckily, I quite enjoy my job.
