Query: One word: Phenomenal!

This book gave me a brand new perspective on how successful careers are made. It's not the typical "you can do it if only you believe" self-help book. It actually provides specific, actionable, and most importantly realistic, ways in which one can develop his own path to success and satisfaction. A must read for anyone who values career success, from new college grads to seasoned executives looking for their next challenge. It's like sitting in a room with Lou Gerstner, Meg Whitman, and Jack Welch and having them divulge the real secrets of their success outside of the obvious. The authors are geniuses!
