君子有三种事应该加以警戒：年轻的时候，血气还没有固定，力戒贪恋女色；到了壮年时期，血气正旺盛，力戒逞强好斗；到了老年时期，血气已经衰弱，力戒贪得无厌。

Not for the sake of our health, though it's often presented that way, but because it's an escape from the human anthill. It's an escape from our own competition, and our own dramas. And that's why ween joy looking at glaciers and oceans, and contemplating the Earth from outside its perimeters, etc. We like to feel in contact with something that is non-human, and that is so deeply important to us.

Don't bend; don't water it down; don't try to make it logical; don't edit your own soul according to the fashion. Rather, follow your most intense obsessions mercilessly.

可持续性不仅仅是关于环境，它还关乎人。
