To study and constantly, is this not a pleasure? To have friends come from far away places, is this not a joy? If people do not recognize your worth, but this does not worry you, are you not a true gentleman?
Don't worry if people don't recognize your merits; worry that you may not recognize theirs.
Do not worry about holding high position; worry rather about playing your proper role.
Riches and honor are what everyone desires, but if they can be gained only by doing evil, they must not be held. Don't worry about not being in office, worry about qualifying yourself for office. Don't worry that no one knows you, but seek to be worthy of being known.
Don't worry that other people don't know you; worry that you don't know other people.
A good man does not worry about not being known by others, but rather is concerned about not knowing them.
If you don't know how to serve men, why worry about serving the gods?
The person of benevolence never worries.
Don't worry about being acknowledged by others; worry about failing to acknowledge them.
Worry not that no one knows of you; seek to be worth knowing.
Do not worry if others do not understand you. Instead worry if you do not understand others.
