Good point! and if you consider the perspective of a budding genius in school as opposed to a budding non-genius, in response to a challenging school topic:
budding non-genius: "this is so hard! i must be dumb"
budding genius: "this teacher hasn't a clue, i'll figure it out later"
and they travel their respective paths.
I think a genius is someone that just chose not to be dumb.
It is quite a wise choice. Whether we can agree on a benchmark constituting dumb remains to be seen but, an interesting observation, none the less...
...while I tend to think that geniuses don't choose their predestiny, to be what they are born as, they certainly have a choice in how they end up !!!
