No! is one of those books that you simply must read. It isn't a book about assertiveness or any of the other things you've read, but a powerful book about taking and maintaining control of your life personally and professionally.

Ask yourself these questions:

Do you say yes when you really want to say no?
Do you ever feel bad when you say no?
Do accept invitations to be on boards and committees even when you are already wildly over committed?
Do you wish there was a way to say no without hurting people's feelings?
Have you ever wondered how and when to fire a customer?

If you answered yes to even one of those questions, then there are literally dozen's of other situations that this book will help you overcome with efficiency.
