Many of us, if not most, wind up in a career in a field one didn’t major in. Even so, choosing that major was not a waste of time. We would all like to know your own career path and how you nevertheless benefited.
In my own case, I was a math major, though I hardly ever make direct use of the math courses I took. Nevertheless, studying math has been extremely useful. What I learned in math was, that to solve a given problem, I often wound up generalizing the problem, solving *that* problem, and applying it to the given problem.
This generalize-solve-apply method is hardly confined to mathematics. I maintain that math emphasizes this more than any other field does. (Physicians and nurses, by contrast, perform the art and science of diagnosing the breakdown of a complex system. Engineers, on the other hand, learn to use approximate rules of thumb, in nearly complete contrast to math, where exactness is the order of the day. Economists concentrate on specifying the exact cost and choice situation, which is sadly uncommon.
In my work, I habitually ask what is the purpose of my assignment. Most of the time, it seems, I can’t get any very good data to discharge my assignment. But if I know the purpose, I can try to furnish something else that will be useful, which is often the case.
So give us all some stories about how your major proved to be useful to the work you do in a field far removed from your major.
