有机体塑造心灵，正如心灵塑造行为。
"The organism shapes the mind as much as the mind shapes behavior."
The actions of men are the best interpreters of their thoughts.
生命可以归结为一种简单的选择：要么忙于生存，要么赶着去死。
You must take personal responsibility. You cannot change the circumstances, the seasons, or the wind, but you can change yourself. That is something you have charge of.
