快乐是最高的善，我们追求快乐，避免痛苦。
没有了目的，生活便郁闷无光。
伟大的工程以你不理解的方式解决你未曾意识到的问题。
It wasn't only wickedness and scheming that made people unhappy, it was confusion and misunderstanding; above all, it was the failure to grasp the simple truth that other people are as real as you.
【译文】 孔子说：“温习旧知识时，能有新收获，就可以做老师了。”
我仍然渴望更多的成功。
