Business books or Real Estate Books?

[Tom Bukacek]

I was going over the 5 most recent educational books I've read, and all books were either business improvement relation, economy related, or self development related. I can't actually think of the last time I read a real estate focused book.

My question is do most investors read about real estate or business building? Also, what is the most recent book you've read and would your recommend it to another?
