I bought this book as a newly promoted USMC Corporal nearly twenty years ago, and have re-read or flipped through it countless times since then. If you're a leader, manager, or supervisor of any sort who cares about your people and want a thorough yet easy to read book that isn't afraid to ask and answer the hard questions, you need this book.
