I can, therefore I am.

If you're going through hell, keep going.

Quality is not an act, it is a habit.

Be gentle to all and stern with yourself.

Begin to be now what you will be hereafter.

Things do not happen. Things are made to happen.

You never know what motivates you.

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

Without hard work, nothing grows but weeds.
