I can, therefore I am.

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

It's always too early to quit.

Always desire to learn something useful.

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

To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

What you do today can improve all your tomorrows.

Be gentle to all and stern with yourself.
