There is a noble manner of being poor, and who does not know it will never be rich.

The acquisition of riches has been to many not an end to their miseries, but a change in them: The fault is not in the riches, but the disposition.

Pleasure dies at the very moment when it charms us most.

Be harsh with yourself at times.

How much better to pursue a straight course and eventually reach that destination where the things that are pleasant are the things that are honorable finally become, for you, the same.

The place one's in, though, doesn't make any contribution to peace of mind: it's the spirit that makes everything agreeable to oneself.

We must take care to live not merely a long life, but a full one; for living a long life requires only good fortune, but living a full life requires character. Long is the life that is fully lived; it is fulfilled only when the mind supplies its own good qualities and empowers itself from within.
