这是最好的时代，这是最坏的时代。

The pain of hard work is temporary, but the regret of not trying lasts forever.

Man is the creator of his destiny, not its slave.

The wild is a place of danger. To survive, you have to respect it.

The key to nudge is to make it easy for people to make better choices.

如果你因失去了太阳而流泪，那么你也失去了群星。
