It's always too early to quit.
Who seeks shall find.
I can, therefore I am.
Be thine own palace, or the world's thy jail.
To be a good loser is to learn how to win.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
What you do today can improve all your tomorrows.
To know oneself, one should assert oneself.
Either you run the day or the day runs you.
I think it is most important for a teacher to play the pieces and studies that are being played by the student.
