大海不拒绝各种各样的水，所以才能成就它的博大；大山不拒绝形形色色的土石，所以才能成就它的高峻；贤明的君主不嫌弃百姓，所以能够聚集众多的臣民；读书人不厌倦学习，所以能达到圣贤的境界。

The only way to get better is to keep doing it.

追求卓越是一段永无止境的旅程。

When you are stuck， explain your problem to others. Often simply laying out a problem will present a solution. Make “explaining the problem” part of your troubleshooting process.

An excellent man; he has no enemies; and none of his friends like him.
