From the Analects of Kǒng Fūzǐ (15:19), who is frequently Anglicized as Confucius:

Ames & Rosemont: The Master said, “Exemplary persons are distressed by their own lack of ability, not by the failure of others to acknowledge them.”

Lyall (Proj. Gutenberg): The Master said, His shortcomings trouble a gentleman; to be unknown does not trouble him.

Legge: The Master said, “The superior man is distressed by his want of ability. He is not distressed by men’s not knowing him.”

A. Charles Muller: The Master said: “The noble man suffers from his own lack of ability, not from lack of recognition.”

So the next time you’re thinking you don’t get enough comments…
