When the cup of any sensual pleasure is drained to the bottom, there is always poison in the dregs.

Imparting knowledge is only lighting other men's candles at our lamp without depriving ourselves of any flame.

The best manner of avenging ourselves is by not resembling him who has injured us.

Guilt is a spiritual Rubicon.

How different is the ready hand, tearful eye, and soothing voice, from the ostentatious appearance which is called pity.

A sincere acquaintance with ourselves teaches us humility; and from humility springs that benevolence which compassionates the transgressors we condemn, and prevents the punishments we inflict from themselves partaking of crime, in being rather the wreakings of revenge than the chastisements of virtue.

Don't live to please others. Don't think everyone else knows what's right or true. Listen to yourself, and be true to yourself. That way, no matter what else happens in life, you will always have your self-respect.
