Authenticity is everything! You have to wake up every day and look in the mirror, and you want to be proud of the person who's looking back at you. And you can only do that if you're being honest with yourself and being a person of high character. You have an opportunity every single day to write that story of your life.

When I worked for Planned Parenthood, we had a specific protocol that we had to follow when picking up our abortion doctor. Looking back, I realize how crazy this was, but at the time, I felt like I was a part of some super secret high-level security task force.

Certainly when I got to medical school, I had role models of the kind of physicians I wanted to be. I had an uncle who, looking back, was probably not the most-educated physician around, but he carried it off so well.

Looking back on it, I'm extremely blessed to play on two very good teams, with great quarterbacks and owners.

I've been painting and drawing fish since I was very young. My mom found old pictures I did when I was around 6 or 7 of all these sharks and scuba diver looking back, a big ship, throwing a harpoon. There was already a message within what I saw.

Looking back at all of my defeats, the only real punishment that I've taken in this sport was against Maidana. I got a fractured jaw.

When we moved to Europe when I was a teenager, I really did not want to go. I was happy in my school, with my friends, but looking back on it, it was the best experience I've ever had. We traveled every weekend. I experienced incredible new cultures, museums, cities, and it really opened up my eyes.

For me, I find that even though I've accomplished a few things in my life, looking back on accomplishments doesn't give me a sense of satisfaction.

I feel privileged and honored to have flown. It's been a tremendous ride, looking back on the legacy and accomplishments, like the Hubble telescope and the launching of the International Space Station in 1998.
