He who sling mud, lose ground.
There is only one thing in life which never changes, and it is change.
Happiness does not consist in having what you want, but in wanting what you have
The real fault is to have faults and not amend them.
The faults of a superior person are like the sun and moon. They have their faults, and everyone sees them; they change and everyone looks up to them.
The superior man is intelligently, not blindly, faithful.
