It's always too early to quit.
Wherever you are - be all there.
Things do not happen. Things are made to happen.
Expect problems and eat them for breakfast.
Begin to be now what you will be hereafter.
Never complain and never explain.
Quality is not an act, it is a habit.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
Be kind whenever possible. It is always possible.
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.
