I've just finished my 20th book this past year and I'm working on my 21st book about the Middle East right now that I'll finish this year. And I get up early in the morning and when I get tired of the computer and tired of doing research I walk 20 steps out to my woodshop and I either build furniture or paint paintings. I'm an artist too.
And I remember going to the record studio and there was a park across the street and I'd see all the children playing and I would cry because it would make me sad that I would have to work instead.
