Take a Break Answer:
Although this quote has frequently been attributed to Abraham Lincoln, he never said it.
It is traced back to a man named Edward J. Stieglitz. An advertisement for Mr. Stieglitz’s book, The Second Forty Years, contained the phrase, "The important thing to you is not how many years in your life, but how much life in your years!"
Don't feel bad if you thought Lincoln said this. His own party did, too.
