@Nafrondel Well, you definitely have an effect on the people you talk to, the world you live off, and almost anything you come in contact with. I'm not sure what lofty way you've defined meaning, but I'd say those effects probably have meaning to someone else.

You don't have to change the whole world, but I'm sure you've probably at least made some progress on making those interactions good ones.

What else are you looking for?
