译文：脾气暴躁，性格偏执，多是短命之人；言语尖酸刻薄，一定是福薄之人。赏析：为人处世一定要温和低调，接人待物要温柔敦厚。脾气暴躁，戾气太重，说话尖酸刻薄，一定会招致很多人的讨厌。被人讨厌，自然身边缺少朋友，何谈有福气呢。

Always keep your knife sharp, your wits sharper, and your spirit sharpest.

The true value of a tree isn't in its board feet, but in its roots and reach.

The well bred contradict other people.The wise contradict themselves.

我从未输过比赛，只是时间不够了。

勇敢是美德之首。
