Imam Ali - Peak of Eloquence (Nahjul Balagha)

148. One who does not realize his own value is condemned to utter failure. (Every kind of complex, superiority or inferiority is harmful to man).

205. A greedy man will always find himself in the shackles of humility.

The sin which makes you sad and repentant is more liked by Allah than the good deed which turns you arrogant.
