To this day, I am saddened by Ranger Tillman's death, as I am for the loss of every service member I served with, and for the pain such losses cause each family.

I am working and improving every day, and I am happy with my work.

I am a businessman. This is what I do each and every day. I love it. I love coming to work. I never have a bad day.

I find that if the day is terrible but I worked out, at the end of the day I can go, 'Well, I had a good workout'. Almost no matter what happens.

We should get to the business of providing at least one million opportunities each year for young Americans to spend a service year with peers who are different from them - by race, ethnicity, income, politics and religious belief.

I don't miss the bureaucracy of being in the Army. But I still love the relationships you can build. And it doesn't have to be in military service - it can be anything you're doing with someone that matters. You develop a bond.
