To be a good loser is to learn how to win.
The wise does at once what the fool does at last.

Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
Diversity in the world is a basic characteristic of human society, and also the key condition for a lively and dynamic world as we see today.
