re: Rental Property Investment

For some of you seasoned real estate investors, where or what was the best knowledge building activity for you? Obviously it would be hard to pick just one, but was it a certain book? Joining an investment club to get to talk to more experienced investors? Family or friends?

Also, what is you favorite real estate book? I've pretty much read every general "investment" book from Warren Buffets Essays on Corporate America to The Intelligent Investor, but I feel like I haven't found a consensus on the better real estate books with there being so many.
