那么。我们应当如何建立出自己的意志，而不会变得固执呢？

So... how do we develop our will, without becoming willful?

我是个乐观主义者，但并不盲目乐观；我有坚强的意志，但并不固执；我自信，但并不自负。

I am an optimistic doctrine, but not the blindness is optimistic; I have a strong will, but not stubborn; I am self-confident, but not complacent.

这双手诉说着人类的固执，也诉说着人类在自我力量范围之内以及超越自我力量的局限乐于工作的意志。

These hands spoke of the stubbornness of mankind, of the will to work not only as one's strength permits but beyond the limits of one's power.
