If you've read the author's other book "What Every BODY Is Saying," you'll find some repetition in the beginning of this book. This book is exactly what its title purport it to be - take your career from average to exceptional. Many of the observations that the author makes about businesses and individuals are obvious, like customers get upset when there's only one cashier to handle a long line and when another worker is called, the worker strolls to his station. Managers should be training their workers to be more responsive to customers if they want to keep their business. I think this book is still worth reading. Even if there is only a few good suggestions that you would apply, practicing some good work habits would improve your performance.
