Wherever you are - be all there.
Never complain and never explain.
Know or listen to those who know.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
Always desire to learn something useful.
The most effective way to do it, is to do it.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
Things do not happen. Things are made to happen.
A good teacher must be able to put himself in the place of those who find learning hard.
