Things do not happen. Things are made to happen.
It's always too early to quit.
Do not weep do not wax indignant. Understand.
The wise does at once what the fool does at last.
Always desire to learn something useful.
You never know what motivates you.
Quality is not an act, it is a habit.
Be gentle to all and stern with yourself.
Wherever you are - be all there.
Only the educated are free.
Whenever death may surprise us, let it be welcome if our battle cry has reached even one receptive ear and another hand reaches out to take up our arms.
