I know you mentioned that he's part scummy, used car salesman, but when does that part go away? You really shouldn't open a book that you actually want people to finish with 50 pages of boasting about how naturally awesome you are at literally everything, and how your life is a perpetual cycle of falling ass-backwards into giant piles of money and women. There are actually a ton of books that start like this and most of them don't contain anything of value, so I assumed that this one was the same.
Seriously though, does it get any better?
