I'd like to add a few in here as well.

The Power of Empathy -- Oh My God. That's all I can really say. This book is amazing.

How to talk so kids will listen, and listen so kids will talk. Terrific book on communications with ANYONE. Get. Read. Live.

As surprising as the title is, "Make Every Girl Want You". Great book on applying many of the DR principles to every day life.

Hope these help someone.
