I'm always reading many books at a time. It might be quite unorthodox, but what I do is, since I'm always surrounded with books, I'll read a page of physics, and then I'll read a chapter of a novel that I really love, and then I'll say, "Oh well, what does that mixture do in my head?" I adore reference books. I love encyclopedias. I also like just going back to original texts, because a lot of these self-help books today.
People ask me all the time what or who my influences are. To be honest, it would take a decent set of encyclopedias to get them all down. I am here today to let the world know my greatest influence, my secret ingredient, really. What inspires me? That's simple: COFFEE.
[My wife] liked to collect old encyclopedias from second-hand bookstores, and at one point we had eight of them. When I wrote my first historical novel---back in 1980, before I was online---I used them often as a research tool. For instance, I learned that the Bastille was either 90 feet high or 100 feet or 120 feet. This led me to formulate Wilson's 22nd Law: 'Certitude belongs exclusively to those who only look in one encyclopedia. '
Elvis is my religion. But for him, I'd be selling encyclopedias right now.
