I’m not depressed (at the moment, well maybe a little), just feeling philosophical.
Edit: the idea of this came to me because I was pondering why people fight so hard to beat diseases and live a few more years. What are they planning to do? Why exert effort just to be here longer when you don’t have a reason?
Just why?
It’s what you make of it. Some people don’t make anything with theirs.
Personally, for me it’s to form community and to leave a positive lasting influence on others. Except fascists, they can rot in hell. For others, it might be to learn as much as they can or to impart their wisdom onto their children.
