A few years ago, I had the co-author of The Go-Giver (Bob Burg) as a guest on my podcast. 

I've referenced that interview (and the book) often on the show - and today I got to interview Bob's co-author for it.  

John David Mann has sold two million copies of his books, and he shared lots of gold nuggets for coaches in this interview. 

You can have a listen here: 

Enjoy,
