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.

Never risk more than you can afford to lose.

I try to get rid of people who confidently answer questions about which they don't have any real knowledge.

The truth is a weapon, and like any weapon, it can be used for good or ill.

与其控制你的生活以避免意外，不如去迎接意外。
