I can, therefore I am.

What you do today can improve all your tomorrows.

You never know what motivates you.

Do not weep do not wax indignant. Understand.

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

Always desire to learn something useful.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

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