Abe Lincoln -- productivity geek

In commemoration of Honest Abe's 200 birthday, Michael Leddy of Orange Crate Art ran this quote from the great President on avoiding procrastination:
Leave nothing for to-morrow, which can be done to-day. Never let your correspondence fall behind. Whatever piece of business you have in hand, before stopping, do all the labor pertaining to it which can then be done.

From "Notes on the Practice of Law," in The Portable Abraham Lincoln, edited by Andrew Delbanco (New York: Penguin, 2009), 33
