Our heroes are human heroes. That's a very new situation. Most other societies have had, right at their center, the worship of something transcendent: a god, a spirit, a natural force, the universe, whatever it is -- something else that is being worshiped. We've slightly lost the habit of doing that, which is, I think, why we're particularly drawn to nature.

The thing about life is that it's never the way you think it's going to be.

Sustainability is not just a trend, it's a responsibility we owe to future generations.

I know that I can always improve, no matter how good I get.
