Pretty useless, and that is to put a pretty face on it. This books is only marginally better than Lamberts previous trial in this area. It tries to cover less ground, skips some of the anecdotes (and now plagiate from others) and tries to give one impression on the book cover (a book for buyers) that doesn't match the internals (which are totally consultant oriented).

Hopefully, Lambert manages to get some customers out of this, as he obviously earns money from the sales of the book, when idiots like myself buys it!

In short, pure crap.
