If you think you can do it, you can.
Be gentle to all and stern with yourself.
Well done is better than well said.
Without hard work, nothing grows but weeds.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
I can, therefore I am.
What you do today can improve all your tomorrows.
Try as hard as we may for perfection, the net result of our labors is an amazing variety of imperfectness. We are surprised at our own versatility in being able to fail in so many different ways.
