What you do today can improve all your tomorrows.
If you think you can do it, you can.
If you've got a talent, protect it.
Quality is not an act, it is a habit.
The wise does at once what the fool does at last.
Always desire to learn something useful.
Only the educated are free.
Do not weep do not wax indignant. Understand.
Things do not happen. Things are made to happen.
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.
