Things do not happen. Things are made to happen.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Be kind whenever possible. It is always possible.

If you think you can do it, you can.

I can, therefore I am.

The dog that trots about finds a bone.

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

By failing to prepare, you are preparing to fail.
