O Contentment, make me rich! for without thee there is no wealth.

The heart is like a musical instrument of many strings, all the chords of which require putting in harmony.

Be thou good thyself, and let people speak evil of thee; it is better than to be wicked, and that they should consider thee as good.

Whoever acquires knowledge but does not practice it is as one who ploughs but does not sow.

Expose not the secret failings of mankind, otherwise you must verily bring scandal upon them and distrust upon yourself.

O Contentment, make me rich! for without thee there is no wealth.

It's no virtue to gain the whole world. Just gain the heart of one person.
