Be gentle to all and stern with yourself.
After a storm comes a calm.
It's always too early to quit.
Without hard work, nothing grows but weeds.
I can, therefore I am.
Only the educated are free.
What you do today can improve all your tomorrows.
Well done is better than well said.
Quality is not an act, it is a habit.
If you think you can do it, you can.
Animals, in their generation, are wiser than the sons of men but their wisdom is confined to a few particulars, and lies in a very narrow compass.
