I don't think I have a 'favorite' author, but I can name a few whom I'm quite fond of. Wayne Dyer, Dale Carnegie, Ayn Rand to name a few. For me, authors attain 'favorite' status during certain points in my life, usually when I'm going through something / need an escape. However, it's easy to forget their influence on you once you've put a book down. I've never actually gotten into Shakespeare except while in school, I'll have to check some of his stuff out again!
