This is so true, and something ethe most depressed of people couldn't argue against! Even if you're not making anything particularly better, you are making it more interesting. Everyone contributes to the world and therefore makes it a little different with each think they do. Everyone has stories and memories and has created memories within others. Everyone makes the world a little more interesting.
(My sister loves this. It just took a long time to favorite it.)
