Do you end up doing what other people want you to do because you don't want to be thought of as a jerk, a meanie, or just downright rude? Do you often hear yourself saying you'll do something you absolutely do not want to do? Do you fail to look out for your own best interests in the same way you'd counsel anyone you love to do?
If you are sitting there nodding your head in agreement you need to buy this book. I read this book many years ago and sometimes I go back to it and read parts of it again. I'd suggest it to any other person on the planet.
The author deserves a gold medal in the humanities.
