领导力是关于用勇气和同理心做出艰难的决定，即使这些决定不受欢迎。

我不害怕表明立场。

We don't inherit the earth from our ancestors; we borrow it from our children.

But it is the same with man as with the tree. The more he seeks to rise into the height and light, the more vigorously do his roots struggle earthword, downword, into the dark, the deep - into evil.
