己所不欲，勿施于人
Don’t do unto others what you don’t want others to do unto you。
有朋自远方来，不亦乐乎？
Is it not delightful to have friends coming from distant quarters？
言必信，行必果
Keep what you say and carry out what you do。
后生可畏，焉知来者之不如今也？
A youth is to be regarded with respect. How do you know that his future will not be equal to our present？
不患人之不己知，患不知人也
I will not be afflicted at men’s not knowing me; I will be afflicted that I do not know men。
