Something human worth doing

You can avoid it, of course. Gotta choose. Give Sartre his due.

The concept of the project I find useful. Something you do in the present, and can remember doing in the past, and expect to do in the future, in order to create something. A work of art which need not be in the arts per se, but something human worth doing.
“That's existentialism, yes?” “Yes, I think that's right. I don't see how you can avoid it.” Kim Stanley Robinson, 2312
