It's always too early to quit.
Only the educated are free.
Never complain and never explain.
What you do today can improve all your tomorrows.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
Problems are not stop signs, they are guidelines.
Always desire to learn something useful.
To know oneself, one should assert oneself.
Quality is not an act, it is a habit.
Dreams say what they mean, but they don't say it in daytime language.
Good teaching is one-fourth preparation and three-fourths pure theatre.
