Dennis is a great man with great ideas. I love him. Go to the above link and watch his talk on gratitude, and how important it is to be grateful. It's indeed eye opening. That's what I love about Dennis. His ideas are so simple, but are full of common sense.
BTW, I have a subscription to his radio show. I listen to his radio broadcasts commercial free any time I choose. There is a fee, but I do recommend listening to Dennis. The free version is listening to him live on radio, 870 AM in LA--Mon to Fri.
