I ddn't finish yet because I am studying it, not reading it; so far is changing my way of thinking. I wanted to say that this book deserves a special kind of attention, exactly because of the mix of tales/cases with insights and really valuable information. As you dig in it, pay attention to the little details, read slow, respect the style of the writing. When John writes about Andy, try to there, try to check Andy's book or even consider looking many of the provided references. Get into the real thing that John is taking about and beyond all - allow time for reflection. If you plan to read this is quick catch schemes mode, is not a good read. Thanks to John for helping us all, for being prompt to the people that don't have direct access to you are any time. Thanks to all the resources and people that John mentioned too.
