It's always too early to quit.
The secret of getting ahead is getting started.
Problems are not stop signs, they are guidelines.
You never know what motivates you.
The wise does at once what the fool does at last.
After a storm comes a calm.
Never complain and never explain.
Be gentle to all and stern with yourself.
Quality is not an act, it is a habit.
Without hard work, nothing grows but weeds.
The teacher who would be true to his mission and accomplish the most good, must give prominence to moral as well as intellectual instruction.
