Or another way of looking at it ... We (should) do what we are interested in, rather than what others perceive we should do, or others may perceive as worthy.
My son is exceptionally smart (and I deal with a lot of kids, so I have a reasonable basis to compare). He's only young ... But his strong suit seems to be very involved stories that he makes up. If I were to guess (yes, I'm crystal ball gazing), he'll be a writer. Despite being one of the most academically gifted children I know, he is looking to "only" amount to a writer. If he does, I'll fully encourage that as it has been his keen interest since he was about 2. Mind you, I'll support any constructive interest he has :)
