If you think you can do it, you can.
I can, therefore I am.
Without hard work, nothing grows but weeds.
Begin to be now what you will be hereafter.
Always desire to learn something useful.
Never complain and never explain.
What you do today can improve all your tomorrows.
To be a good loser is to learn how to win.
Be thine own palace, or the world's thy jail.
Be kind whenever possible. It is always possible.
It often takes more courage to change one's opinion than to keep it.
