If you wish to reach the highest, begin at the lowest.
Dr. Joyce Brothers
If your energy is as boundless as your ambition, total commitment may be a way of life you should seriously consider.
It is more important to know where you are going than to get there quickly.
It's never too late to be what you might have been.
I've got a great ambition to die of exhaustion rather than boredom.
Keep away from people who try to belittle your ambitions. Small people always do that, but the really great ones make you feel that you too, can become great.
Keep your feet on the ground and keep reaching for the stars.
Knowing your destination is half the journey.
Daniel H. Burnham
Make no little plans. They have no magic to stir men's blood and probably themselves will not be realized. Make big plans. Aim high in hope and work. Remembering that a noble, logical diagram once recorded will not die.
Make no small plans for they have no power to stir the soul.
