译文：年轻时候的努力是有益终身的大事，对着匆匆逝去的光阴，不要丝毫放松自己的努力。赏析：光阴易逝，岁月不饶人，我们要敢于尝试，敢于拼搏，不要怕失败，即使失败了也会收获很多经验。

Every experiment is a conversation with nature, and sometimes nature whispers its secrets.

To understand behavior, look for the utility in it.

The purpose of all these illustrations is to direct the seeker's mind towards the one reality underlying them all.

（道德高尚的人）明察安危，安于祸福，谨慎地对待去留，就没有什么能够伤害他们。
