If you've got a talent, protect it.
Be thine own palace, or the world's thy jail.
Either you run the day or the day runs you.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.
Never complain and never explain.
Go for it now. The future is promised to no one.
Leap, and the net will appear.
Only the educated are free.
Be gentle to all and stern with yourself.
A teacher must believe in the value and interest of his subject as a doctor believes in health.
A good teacher is a determined person.
