Eudaimonia.

O'Keeffe, Ladder at Abiquiu Ranch, n/d

I think it's so foolish for people to want to be happy. Happy is so momentary--you're happy for an instant and then you start thinking again. Interest is the most important thing in life; happiness is temporary, but interest is continuous.

Georgia also said, "It's not enough to be nice in life. You've got to have nerve.”  What she means is, no balls, no banners ... be the ball.
