Things do not happen. Things are made to happen.

The dog that trots about finds a bone.

I can, therefore I am.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Always desire to learn something useful.

Be kind whenever possible. It is always possible.

To be a good loser is to learn how to win.

Be thine own palace, or the world's thy jail.
