This is a great book, but (sadly) it is for a very limited audience.
While it is short and simply written, and is itself an "easy read", each sentence comes from considerable experience on the part of the author and there are some real pearls of wisdom.
For those who are familiar with the Gift of Fear, Left of Bang, and the sheepdog principle - this book should be on your list. If not, this book probably is not a starter work.
