You never know what motivates you.
Expect problems and eat them for breakfast.
Always desire to learn something useful.
If you think you can do it, you can.
Things do not happen. Things are made to happen.
If you can dream it, you can do it.
Be thine own palace, or the world's thy jail.
Be gentle to all and stern with yourself.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
I travel all over the country making speeches for people I believe in.
Teaching was the hardest work I had ever done, and it remains the hardest work I have done to date.
