If you think you can do it, you can.
If you're going through hell, keep going.
Either you run the day or the day runs you.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
If you can dream it, you can do it.
Well done is better than well said.
Only the educated are free.
The dog that trots about finds a bone.
It's always too early to quit.
Nothing in man is more serious than his sense of humor it is the sign that he wants all the truth.
The art of teaching is the art of assisting discovery.
