To know oneself, one should assert oneself.

I can, therefore I am.

If you think you can do it, you can.

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

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.

Without hard work, nothing grows but weeds.

Leap, and the net will appear.
