a bunch of people who are choosing to keep trying

from the vulture interview with louis ck:

You’re not an insult comic, but I think it’s fair to say that your work generally skews dark. What are you optimistic about? What makes you happy?
Trillions of things. I feel safe talking about dark subjects because they exist in a world full of life and beauty. Everybody who’s alive is choosing to be. You can take yourself out anytime. The whole population is a bunch of people who are choosing to keep trying.
