I Hope They Serve Beer in Hell by Tucker Max

The pick-up artist is married and has three or four children. He moved to Austin, Texas to find the specific woman he was looking for - a nurse who did CrossFit but also worked as a personal trainer. The author says that Tucker Max had an incredibly raucous young adulthood in hooking up in frat parties and things like that. It's written with a notorious guy who wrote a book or he wrote a bunch of books.
