毁灭自己的错误胜过毁灭他人的错误。
It is better to destroy one's own mistakes than those of others.
The most perfect education, in my opinion, is such an exercise of the understanding as is best calculated to strengthen the body and form the heart.
【译文】 孔子说:“君子总是胸怀宽广,小人总是忧愁悲伤。”
Change is hardest in the beginning, messiest in the middle, and best at the end.
