We have to continually be jumping off cliffs and developing our wings on the way down.

We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.

静坐的时候才知道平日的心浮气躁，独自呆着不说话才知道平日言语暴躁多话。反省行为才知道平日心情忙乱，闭门拒绝客友才知平日交友泛滥。少欲望才知道平日多病。近人情才知道平日待人处事的苛刻。

勇气是对恐惧的抵抗和掌控，而非没有恐惧。
