I've often been fascinated about why certain college students choose to pursue certain college majors. The choice of a major, obviously, is important and can supply a direct route to a life's work success and happiness.
Conversely, a certain major may have little or nothing to do with what leads to vocational satisfaction. Engineers can become lawyers, history majors can become surgeons, biologists can end up as FBI agents. The logic of correlation, if there even is a correlation, is hard to track.
