Query: You have got to be kidding?

I endeavor to follow the addage that if you have nothing nice to say then say nothing; however, this work is redundant, virtually devoid of any actionable insights, and smacks of a self indulgent attempt to justify his own ideosycratic work habits. I kept going in hopes that one concept would justify my investment of mind. The only return on my investment is a book I can now confindently refer to those I distain and assiduously warn those I adore to avoid.I am fairly sure the majority of previous reviews are from nodes in his social network who have seized upon his scintilating suggestion that effective knowledge workers maintain and nuture their relationships by treating them well. It is sycophantic myopia when work which could and should be great barely achieves mediocracy receives any praise whatsoever.If Mr. Davenport reads these words please know that I harbor no ill will to you personally I just found this particular publication of your work seriously wanting.
