I can, therefore I am.

Be gentle to all and stern with yourself.

Never complain and never explain.

Begin to be now what you will be hereafter.

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

What you do today can improve all your tomorrows.

The dog that trots about finds a bone.

Go for it now. The future is promised to no one.

Without hard work, nothing grows but weeds.
