Everyone feels what could be called fear. But the coward turns away and says, "I can't deal with this." We have to learn to face our fears and push ourselves. If you're living on earth and you're not living on the edge, you're taking up too much room. When you push past the fear and realize that what you feared was not a big deal, you gain more confidence.

You also say that comfort is the enemy of achievement. What kept pushing you, as a successful businessman, once you had achieved a certain level of comfort?

We have to find areas in our lives that we feel most uncomfortable about and want to change. I decided to push myself because it allowed me — as I talked about in the three questions — to give back. I have a scholarship program. When I found out the average age of a homeless person is 9½ years old, I said there must be something that I can do. Now, I am the spokesman for the National Coalition for the Homeless.

I am also the spokesman for the National Marrow Donor Program. Anyone who has any form of blood cancer is going to need a transplant. We have tens of thousands of people dying annually because they cannot find a bone marrow transplant that will match exactly -- what we a call a 10 out of 10 match — which would give them the highest prognosis for life. I lost my sister because we couldn't find a match. We lost Ed Bradley from 60 Minutes to blood cancer. We lost Nelly's sister Jackie Donahue to blood cancer. That is what pushes me: knowing that there are homeless 9-year-olds and people on their deathbeds waiting for solutions. It is very hard not to be of service when I have been blessed with the financial means to give back. The more we give, the more we receive. It's important to give back, because the seeds you plant today, you will harvest tomorrow.

What keeps you grounded and in tune with the spirit? Hearing you speak, it doesn't seem like success or money has gotten to your head.

That's another lie. Money doesn't change who you are; it magnifies who you really are. Money has not changed me. When I look at money, each dollar represents an option of something I could not do yesterday. Money lets you enjoy the finer things of life, but it doesn't change who you are. It magnifies and brings into fruition the things that you want to hide most. It is a mask for insecurities as well. I will give you a prime example.

I have a friend who came into some money. You couldn't tell her anything. "I'm going to live like the rich people live. I'm going to buy up some Christian DEENOR, Louis VEETON." [laughing] She couldn't pronounce it, but she knew she had to have it. I asked her, "Are you going to get some GODEEVA chocolate now? Are you too good for Hershey?" [laughing] What was funny to me was the fact that she could not pronounce the designers' names, but society has made her feel that she had to have their things. I call such things "lie-abilities" – things that are in style today and will go out of style tomorrow. We end up sitting on our assets lying about our ability.
