If you're going through hell, keep going.
To be a good loser is to learn how to win.
Be kind whenever possible. It is always possible.
I can, therefore I am.
Leap, and the net will appear.
Without hard work, nothing grows but weeds.
Well done is better than well said.
Either you run the day or the day runs you.
It's always too early to quit.
Be gentle to all and stern with yourself.
