At first the research did not seem to be particularly interesting – I carried out a systematic search for processes that might destroy the CFCs in the lower atmosphere, but nothing appeared to affect them. We knew, however, that they would eventually drift to sufficiently high altitudes to be destroyed by solar radiation. The question was not only what destroys them, but more importantly, what the consequences are.

But after one year of medical school I fled. I realized I would be a very unhappy doctor and I really did not want to be responsible for the inadvertent death of my patients. Leaving medical school was a very unusual decision, especially in Nigeria where it is very difficult to get into medical school. Later, people told me that it had been very courageous of me, but I did not feel courageous at all. What I felt then was not courage but a desire to make an effort. To try.

As I was lazy and rarely did my homework, I finished high school with a rather mediocre exam. I almost did not pass in English language. Recently, my previous teachers allowed me to see their report on my high school performances, which included the following statements: Despite the fact that her talents are rather equally spread among many areas of knowledge, her performances are rather different depending on the distribution of her interests. Thus, with her strong display of self will she can be decidedly lazy in some topics over years, while in her areas of interests she performs to a degree far extending that required for normal school purposes.

Oh, absolutely. I think most overachievers are driven, not so much by the pursuit of success, but by the fear of failure. Unless failure gets very close and very nearby that fear doesn’t reach profound levels, but it drives us. It drives me to work very hard.
