Difficulties strengthen the mind, as labor does the body.

We become wiser by adversity; prosperity destroys our appreciation of the right.

Behold a contest worthy of a god, a brave man matched in conflict with adversity

Light troubles speak; the weighty are struck dumb.

The pressure of adversity does not affect the mind of the brave man... It is more powerful than external circumstances.

The bravest sight in the world is to see a great man struggling against adversity.

The good things of prosperity are to be wished; but the good things that belong to adversity are to be admired.

No untroubled day has ever dawned for me.
