Quality is not an act, it is a habit.
It's always too early to quit.
After a storm comes a calm.
The secret of getting ahead is getting started.
If you can dream it, you can do it.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
If you think you can do it, you can.
Do not weep do not wax indignant. Understand.
Either you run the day or the day runs you.
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.
