I think it only inflates the bubble and bubbles burst sooner or later. Only serious, genuine people working on betterment of humanity eventually win.
That's what I like to tell myself.

It does not matter if you are dead before people realise your contribution to the world. For example, Galileo won.
For example, there are people who hold the Scientific Revolution ushered by Galileo&co to be directly responsible for genocides and suffering (of humans and otherwise) on an unprecedented global scale.
In the long-term view suggested by inglor_cz, "change this world a little for good" is really just feel-good moralistic posturing. Without specifying "good for whom?", and "on what time scale?", it's a vacuous concept.
That said, you would benefit from learning about effective altruism, it is a philosophical and social movement that advocates using evidence and reason to figure out how to benefit others as much as possible, and taking action on that basis.
