一起激发的细胞连在一起。

Watch your thoughts, for they become words. Watch your words, for they become actions. Watch your actions, for they become habits. Watch your habits, for they become your character. And watch your character, for it becomes your destiny. What we think, we become.

在这个常常奖励自私的世界里，善良可以是一种革命性的行为。
