I just read the short summary on goodreads [1] and... color me skeptical...
It reads like a version of "The Celestine Prophecy" [2] but aimed at a middle-aged tech bubble. Could you (or anyone else) compare the two, for a very slow reader to make a decision? :D
PS yes the comparison is probably too harsh but that was honestly my first gut reaction...
I believe you reference the wrong "4000 weeks". That one is by a different author. There doesn't appear to be a Goodreads listing for this one yet, but there is on Amazon.
