I can, therefore I am.

What you do today can improve all your tomorrows.

It's always too early to quit.

Either you run the day or the day runs you.

Do not weep do not wax indignant. Understand.

Never complain and never explain.

Without hard work, nothing grows but weeds.

To know oneself, one should assert oneself.

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