Never complain and never explain.
Be gentle to all and stern with yourself.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
Without hard work, nothing grows but weeds.
Who seeks shall find.
If you're going through hell, keep going.
The dog that trots about finds a bone.
Things do not happen. Things are made to happen.
The most effective way to do it, is to do it.
I think it is most important for a teacher to play the pieces and studies that are being played by the student.
