> As a check on his aptitude, a serious-minded student will take courses in several different departments to find out in what field he can do the best work. This is quite distinct from finding out where he can get the best grades... edit: wording Interesting, "[...] in what field he can do the best work" is given as the prime criterion, and not "in what field he can earn the most money" which is given a lot of value today. Arguably, doing the "best work" leads to financial reward, but focus on the latter inevitably sabotages the former. What a strange paradox!
