The culture in which we live stresses looking out for number one. Without adopting such a self-centered value system, we can demand the best of ourselves while we are extending our hands to help others.

One of the reasons surgeons have so much trouble separating Siamese twins is that nobody gets to do many of them. On the table, the anatomy is so different from normal, that you're constantly trying to figure out, 'Can I cut this? Does this wire lead to what?' It's like trying to defuse a bomb.

Tell the truth. If you tell the truth all the time you don't have to worry three months down the line about what you said three months earlier. Truth is always the truth. You won't have to complicate your life by trying to cover up.

I'm not even sure I like surgery, but I like what it does, I like the effects. I like to be able to give people longevity and quality of life, and I also think it's good for people to use the special gifts and talents that they have. And when I was in medical school, when I began to analyze the gifts and talents that I had, I realized that surgery would probably be a very good fit for me.

Always give your best and try to figure out how to do an even better job.

A culture exists within the [Ted] Cruz camp that would allow people to take advantage of a situation like this in a very dishonest way.

I have this feeling that as time goes on, we're not getting any more civilized, and we should be. We're still running around like the days of Genghis Khan. There are so many important, better things to do and we need to encourage people to reach into the brighter side of humanity and not encourage people to continue to glorify the darker side.
