Robin Dreeke's It's Not All About Me makes it easy to build rapport with anyone.
It is one of the most practical books I have ever read. I enjoy reading Khaneman, Ariely and that ilk as much as the next guy, but in this book the author is less interested in what psychological mechanisms are at work (though he does take stabs at them) as he is into what works in what situation.
The book at times reminded me of The Game, a similarly practical book that I highly recommend for anyone who is single. Some of the same techniques are mentioned in both books.
I can't say any of the methods suggested in in It's Not All About Me were totally unknown to me. I knew them all in some form or another. But conquering the biases in the brain that prevent one from carrying out some of these techniques remains the most challenging hindrance to mastering this field, in my opinion.
If you're in sales or in a line of work that requires building rapport, I highly recommend the book.
