"Leave nothing for tomorrow which can be done today."
"Beware of rashness, but with energy, and sleepless vigilance, go forward and give us victories."
"Every day you may make progress. Every step may be fruitful. Yet there will stretch out before you an ever-lengthening, ever-ascending, ever-improving path. You know you will never get to the end of the journey. But this, so far from discouraging, only adds to the joy and glory of the climb."
"The struggle for today is not altogether for today -- it is for a vast future also."
"However beautiful the strategy, you should occasionally look at the results."
