For me, it would be that I smoke weed
Maybe at your age. At my age almost all of the Something Great bells have rung. Don’t get me wrong, there are still plenty of very meaningful things i can accomplish, and many important impacts i can make on individual people’s lives, - but for me the possibility of doing something that has a broader impact on society is pretty much gone. But so what, the impact i can have on individual people’s lives is still very valuable, and my own subjective experience of life is just as important as anyone else’s! So i try to make my own experience of living as good as it can be!
