生命周期假说认为，个人会在一生中规划其消费和储蓄行为。

我不是为了钱说唱，我是因为热爱。

Every book is a door that opens onto another world, and every reader is a traveler who steps through it.

When we love, we always strive to become better than we are. When we strive to become better than we are, everything around us becomes better too.

圣人与物相处而不伤害，不伤害外物的，外物也不伤害他。正因为无所伤害，才能自然地与人交往。山林啊，大地啊，都能使我欣然快乐。

最好是不失败，其次则是败了却还有办法成功，这才叫善于用人。
