Simon & Schuster The 7 Habits of Highly Effective People: Powerful Lessons in Personal Change

The reasoning behind the book relies entirely on 1) knowable, "correct" principles and 2) anecdotes. If you're willing to consent that there could be such a thing as a "correct" principle then this book may not leave you cringing uncontrollably. However, the way he presents anecdotes as proofs will -- and his attempts to redefine words poetically to shape philosophy is unnecessary in the modern world of psychological studies.

This book is not a must-read. I gave it a 2 out of 5 only because some pieces were unintentionally thought-provoking. I'm certain they were unintentional because they had no context -- although lacking context is apparently a central tenant of his writing. The most powerful quotes from the book are the author quoting someone else. You get a second-hand look at psychology that you'd be better off reading from well-written researchers (see Thinking, Fast and Slow). If any ideas were monumental at the time (1989) they are not now and you'll get nothing more from reading them here.
