Don't say you don't have enough time. You have exactly the same number of hours per day that were given to Helen Keller, Pasteur, Michaelangelo, Mother Teresea, Leonardo da Vinci, Thomas Jefferson, and Albert Einstein.
~ H. Jackson Brown, Jr
The rung of a ladder was never meant to rest upon, but only to hold a man's foot long enough to enable him to put the other somewhat higher.
