幸福是通过美德获得的，是人自己意愿获得的善。
Happiness is secured through virtue； it is a good attained by man's own will.
The line between good and evil is often blurred, and it is up to us to navigate it.
The challenge of leadership is to be strong, but not rude; be kind, but not weak; be bold, but not bully; be thoughtful, but not lazy; be humble, but not timid; be proud, but not arrogant; have humor, but without folly.
我们这个时代的挑战是创造一个可持续的能源未来。
