Is it possible for anything to matter? My teacher always tells me if I do bad in a drama scene, I shouldn't worry about it because no one will remember or care in a few weeks. Doesn't that apply to everything? If I cure cancer, surely that will affect almost everyone on the planet, but will anyone even appreciate it a million years after the fact? A billion? Humans can't last forever, and eventually our species will die - meaning no one will be alive to remember cancer even existed. Even Earth will die eventually. Even the Galaxy!! So how can anything I do be important in the grand scheme of things?
