The benevolent are often schemed against by petty people; the wise are often pushed aside by the mediocre; the brave are often envied by the foolish; and the incorruptible are often attacked by the greedy. A little pressure feels like the world is ending; a little unhappiness makes one feel like the most pitiable person in the world...

One day, if you do not do something, you face others' misunderstanding; one day, if you refuse, you face others' blame.

对于某些事物，时间非常关键。认识得太早或太晚，都不行。
时间就像一条小河，过去了就永远不会回来了。这一秒我干了什么，是我的选择；那一秒我干了什么，谁也不知道，只有那个时候的我才知道。现在你觉得时间不宝贵，等你老了，你就会觉得时间很宝贵。
有一天，你没有做某事，换来的是别人的费解；有一天，你拒绝了，得到的是他人的责怪。没有人会太在意你为了别人，抽出了自己多少的时间；没有人会太关心你为了他人，劳累了自己多少的心神。更没有人考虑：你是否太累了，是否需要偶尔的休息。
