Without hard work, nothing grows but weeds.
Be thine own palace, or the world's thy jail.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
After a storm comes a calm.
Always desire to learn something useful.
Expect problems and eat them for breakfast.
To know oneself, one should assert oneself.
What you do today can improve all your tomorrows.
Quality is not an act, it is a habit.
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.
