If you're going through hell, keep going.
Things do not happen. Things are made to happen.
If you think you can do it, you can.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
Know or listen to those who know.
Well done is better than well said.
If you can dream it, you can do it.
Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.
