I can, therefore I am.
If you can dream it, you can do it.
If you're going through hell, keep going.
Problems are not stop signs, they are guidelines.
Wherever you are - be all there.
Things do not happen. Things are made to happen.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
Well done is better than well said.
What you do today can improve all your tomorrows.
I began even as a boy to realize how wide the world can be for a man of free intelligence.
