"As a child of economists, I knew that economics was one field I must avoid. My father was a famously charismatic teacher, who adored and was much adored by his many students. He would often talk about just how brilliant some of them were, and it was clear to me that I had nothing to gain and much to lose by inviting comparisons with them. In my deeply anti-intellectual high school, it was made very clear that we should all aspire to study engineering or medicine because they led to good jobs (the lure of jobs in finance came many years later). They made an occasional exception, in the case of an unusually brilliant student, for studying phys­ics. I had no desire to be an engineer or a doctor and prepping for physics required consorting with our physics teacher, a man who seem to take genuine pleasure in inflicting pain. What else could I do? I loved literature and history, philosophy and math; my parents were against the first three. Their stated grounds were that I could always go from math to those at a later stage but not the reverse, though my guess now is that they were not sure that I was good enough to make a living in the humanities, given the shape of the labor market. In any case their argument for math appealed to my instinct for trying to postpone all hard choices. Math it was going to be."
