Is it possible to become a genius?
Depends how you define the word like always.
In my opinion however people are defined as 'genius' usually for
what they do rather than what they are.
People can achieve far greater things than they realize, things
sometimes that could give them such a high status as being referred
to as a genius. So in that meaning of the word, where belief in
oneself is the biggest factor, as it would be the asset which
motivates you to such a position, I believe YES it is possible.
However if you consider genius to be some sort of child prodigy
who has an IQ of 180 when they're age six, than no I DON'T, you
just could not keep up or reach such a position as they could in
such a short life, 1 in a billion says you could. However this
version of the word might not ever materialize into anything more
than brains, so you have to ask yourself 'really', why are you
asking such an egotistic question? What your ego wants might not
exactly be as real as what you yourself define as right.
