The easy reading format makes the book a very easy and enjoyable read as well. The book can be started and stopped without ever feeling you've lost your place in the book.
In today's time-constrained work environment this book is easy to read and provides numerous great insights on standing out from the clutter.
Whilst encompassing a wide domain, and attractively packaged (once one gets used to the quirky design) there is little really new here (apart from the anti-Dilbert cynicism movement). Many of the suggestions are contradictory (e.g. both be rude yet network & show empathy; focus on time management & task, yet allow self-to be distracted by random influences etc.. etc..). Peters point is that you can select your own activities ultimately aimed at promoting a positive-outlook, for control of your own destiny, and development of the skills needed to succeed in the uncertain future of work.
Negatively, the book is repetitive, is US-focused (not international-level), has unimpressive bland (to non-US) role-models (Martha Stewart, Oprah et al), and promotes a greed-centred (ask & you will get) `style over substance' message. Extrapolating over society, one simple view could be that you may get many competing, dissatisfied, high-expectation workers all doing similar things (rather than specialising or exploiting economies of scale)- not good.
Overall, a useful recommended book for the increasingly portfolio-worker age.
