When I was very little, I thought it might be possible to be an angel.

A teacher. Teachers can change lives.

An artist travelling and playing with the Stones.

A visual artist.

I did. As a kid, I liked music. I still like it a lot of course. I used to play the violin. I did contemplate, well, maybe that’s an option. I could become a musician. Somehow my parents got some advice that unless I was willing to spend eight or 10 hours a day just playing the violin that I should just give it up. To me, that was very bad advice because you could of course, get very involved in music without being a musician. Fortunately, even though I gave up eventually playing the violin myself, I never gave up my fondness for music. But if I had a chance again, I would not give it up. I would just do it as a hobby. I think that was just because I did not get the correct advice.

The advice that I would give is try to find something that you like. Try to devote your energies to being very good at it. Try to achieve excellence. Don’t necessarily have as a goal success or getting prizes or whatever, but just doing very good work. And work hard. Keep working at it. Be patient. Realize that you don’t always see the benefits of what you’re doing, short-term. But in the end, the activities that I do, for example, scientific research, can be extremely rewarding. It’s really a very fascinating career.

I certainly want to continue trying to understand how the global environment functions. The earth as a system is a very complicated one. And to understand it, we need very many disciplines, very many different scientists working together. I want to continue working with my specialty, which is chemistry, with the atmosphere. There is still much to learn about chemical reactions that occur out there in the air, in the atmosphere. So one of my projects now is to really learn more about this pollution that occurs in cities and that is spreading more through the globe. To learn it in enough detail so we can better tackle it, we can better come up with new ways of using energy, for example, that are not so damaging to the environment.

So achievement, to me, is something that just comes with this attitude of doing your work the best you can in a passionate way. It’s not something that you have to expect. It’s something that’s a consequence of what you do, but it’s certainly important.

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.

I then converted a bathroom, seldom used by the family, into a laboratory and spent hours playing with chemistry sets. With the help of an aunt, Esther Molina, who was a chemist, I continued with more challenging experiments along the lines of those carried out by freshman chemistry students in college.
