You'll waste your life chasing dreams of changing the world. You have presented yourself as a solution looking for a problem.

I am sorry if that seems harsh, but you asked.

From my experiences, positive impacts have never been top-down, or from a place of "addressing societal problems".

Innovation (and motivation) comes from laziness, need, and greed. Instead of solving society's problems, in this regard, just look to your own. Then, the question of "worth" is self evident.
