Don't be scared of the ‘what ifs,’ because the truth is, the only failure is not trying. That's the only way you can fail. Trying and having it not work out isn't failure.

I feel that because I challenge myself so often, sometimes I will fail. This is, to me, the essence of competition — that there will be both winners and losers. But I have great faith in myself that I will turn this loss into something positive.

Day one of my first job out of college, my boss found out that I didn't know how to enter data into Lotus 1-2-3. That's a spreadsheet—ask your parents. His mouth dropped open and he said, ‘I can't believe you got this job without knowing that”—and then walked out of the room. I went home convinced that I was going to be fired. I thought I was terrible at everything… but it turns out I was only terrible at spreadsheets.

I will begin with the importance of learning from experience. It is less important, I believe, where you start. It is more important how and what you learn. If the quality of the learning is high, the development gradient is steep, and, given time, you can find yourself in a previously unattainable place. I believe the Infosys story is living proof of this. Learning from experience, however, can be complicated. It can be much more difficult to learn from success than from failure. If we fail, we think carefully about the precise cause. Success can indiscriminately reinforce all our prior actions.

I have also benefited from teaching; as I try to explain my views to students with critical and open minds, I find myself continually being challenged to go back and rethink ideas. I now see teaching and research as complementary, mutually reinforcing activities.

For me, it was just a thrill. I just remember thinking at that time, this is the sort of thing I would like to do, if I could. I did not come from a family of scientists. My father was a lawyer, my older brother was a lawyer.

Certainly not. As a young child, I remember just dreaming about the Nobel Prize, but that was just a dream. It’s not something I would have ever thought was possible for me.

there are really very many. Again, as a child, it was obviously those scientists which had lived in the past that had made such an important mark in science history.

I had a number of very good teachers in high school, in fact. Some mathematics teachers that perhaps allowed me the freedom to go beyond the normal routine of the class and to explore some more advanced areas. The same thing happened in college. I was able to communicate with a few of my teachers and professors, and go beyond the normal expectations. And then, as I mentioned before, Professor Pimentel, my mentor for graduate studies, was really influential in terms of the influence that he had for me.

In terms of this issue of these industrial gases affecting the environment, at the beginning the road was not easy, because we were suggesting that society had to change, that industries had to do something different than they were doing at that time. And of course, initially we did not meet with a good reception to these ideas from industry. And even from the scientific community — even though our ideas were well received in the small group of specialists in what we were doing — it was not necessarily well received by the scientific community at large. So we really had to continue doing as good a science as we could, and at the same time trying to well communicate our conviction that it was something important, something that had to change in the way society was functioning.
