I love this book. I read it 20 years ago and still use many of the ideas. Nowadays, I am most excited by Optimal Thinking: How to Be Your Best Self and Crucial Conversations. Optimal Thinking shows you how to be your best no matter how difficult the situation. If you are facing an abusive person, a passive-aggressive, or any conflict, you learn how to be your best. Crucial Conversations shows you how to deal with difficult conversations. Buy and read these three books!
