Keep learning as much as you can about wholesaling by asking questions, reading others forum posts, listening to podcasts, and reading books and blog posts abouy the subject (I do podcasts and audio books through audible on amazon in the car to work everyday), 3.

And also think about book like The Millionaire Next Door that debunk myths about wealth in the US (a bit dated, but the book's data tells us someone like a landlord in the old pickup in overalls mowing the lawn at the duplexes may be your high net worth person in America; not the flashy professional investor guy in the high end luxury sedan with a Rolex).....

I began by talking to people who then referred me to bigger pockets :) and purchased a few real estate books some of which some I still have not finished.  

@Brandon Turner actually wrote a whole book on the subject and it's a very worthwhile read:http://get.biggerpockets.com/nomoneydown/Here are a few tips to help you get the most out of BP and kickstart your investing career:Start here.

I highly recommend the Book on Flipping Houses by J Scott who is a big contributor to BiggerPockets and a true real estate pro.  

I second the suggestion on the podcasts but there are also very good books to read on RE and business that will really help.  

I just got @Brandon Turner's book on no/low money down investing.

As a side note, the term BRRRR seems to be relatively new but I'm reading a book from 2005 and the strategy discussed in it is exactly the same.

Listen to the podcast and read a couple of books on realestate investing.

I would recommend reading a little book that is just about the best book ever written about wealth creation called, "The Richest Man In Babylon" by George S Clason.
