A man's worth is no greater than his ambitions.

A man's worth is no greater than the worth of his ambitions

Nowhere can man find a quieter or more untroubled retreat than in his own soul.

A man’s worth is no greater than the worth of his ambitions.

The man of ambition thinks to find his good in the operations of others; the man of pleasure in his own sensations; but the man of understanding in his own actions.

A noble man compares and estimates himself by an idea which is higher than himself; and a mean man, by one lower than himself. The one produces aspiration; the other ambition, which is the way in which a vulgar man aspires.
