Time

I love this quote by H. Jackson Brown Jr.

"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, Michelangelo, Mother Theresa, Leonardo da Vinci, Thomas Jefferson and Albert Einstein."

Another quote I love by Alice Bloch:

"We say we waste time, but that is impossible. We waste ourselves."
