It's always too early to quit.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
What you do today can improve all your tomorrows.
Do not weep do not wax indignant. Understand.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
I can, therefore I am.
Things do not happen. Things are made to happen.
Quality is not an act, it is a habit.
Why fear death? It is the most beautiful adventure in life.
When you consider all the stars I have managed, mere submarines make me smile.
