A healthy forest is a resilient forest.

The first fruit of this imagination - and the first lesson of the social science that embodies it - is the idea that the individual can understand his own experience and gauge his own fate only by locating himself within his period, that he can know his own chances in life only by becoming aware of those of all individuals in his circumstances.

世上任何卓越的成就都缺不了熱情。

All men are created equal.

幸福不能被追求；它必須隨之而來。

我認為不斷學習和成長是很重要的。
