To know oneself, one should assert oneself.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

Be kind whenever possible. It is always possible.

The wise does at once what the fool does at last.

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

If you're going through hell, keep going.

Things do not happen. Things are made to happen.

Who seeks shall find.
