I've always felt that I did well as a student because I lacked confidence.

So much goes into doing a transplant operation. All the way from preparing the patient, to procuring the donor. It's like being an astronaut. The astronaut gets all the credit, he gets the trip to the moon, but he had nothing to do with the creation of the rocket, or navigating the ship. He's the privileged one who gets to drive to the moon. I feel that way in some of these more difficult operations, like the heart transplant.

I think work is a privilege. ... It keeps you alive, spiritually.

The spirit of Texas seems to pervade our everyday existence. Our desire is to be superlative, not only the largest, but also the best in the United States.

I've always felt that maybe one of the reasons that I did well as a student and made such good grades was because I lacked confidence. Lacked self-confidence, and I never felt that I was prepared to take an examination, and I had to study a little bit extra. So that sort of lack of confidence helped me, I think, to make a good record when I was a student.

[The heart is] really a fascinating organ. It's about the only organ in the body that you can really witness its function. Doing things. And so on. Some of the other organs you can witness, like the intestines, will have this sort of peristaltic motion. But nothing that can compare with the activity of the human heart.

I still take failure very seriously, but I've found that the only way I could overcome the feeling is to keep on working, and trying to benefit from failures or disappointments. There are always some lessons to be learned. So I keep on working.
