Rest is by no means a waste of time.

To render ourselves insensible to pain we must forfeit also the possibilities of happiness.

Be cautious, but not too cautious; do not be too much afraid of making a mistake; a man who never makes a mistake will make nothing.

We may sit in our library and yet be in all quarters of the earth.

Those who have not distinguished themselves at school need not on that account be discouraged. the greatest minds do not necessarily ripen the quickest.

Men are more helped by sympathy than by service.

Do not lay things too much to heart. No one is ever really beaten unless he is discouraged.
