Fear is the main source of superstition， and one of the main sources of cruelty. To conquer fear is the beginning of wisdom， in the pursuit of truth as in the endeavour after a worthy manner of life.

I'm not going to compare myself to anybody. I'm going to do the best I can do. I'm going to work as hard as I can work. And I'm going to be the best that I can be.

你自己，就像整个宇宙中的任何人一样，值得你的爱和关怀。

可持续性不是一种选择；而是我们对后代的责任。
