你唯一应该超越的人就是昨天的自己。
The only person you should try to be better than is the person you were yesterday.
I declare after all there is no enjoyment like reading! How much sooner one tires of any thing than of a book!
We should cultivate indifference to everything.
做伟大的事情很困难，但指挥伟大的事情更困难。
没有什么比一项未完成的任务永远悬在那里更令人疲惫的了。
