The doors on my desk hutch at work are painfully bare. I'd like to make up some 8.5X11s with various GTD "Pearls of Wisdom" to provide inspiration when I need it. Things like, "If it's on your mind, it's not getting done" from OpenLoops. I also have an ulterior motive, in that my desk is against the outside wall of the room, with my back to the middle of the room, and it's an open room with about 7 other people working in the same space. I'm looking to "infect" at least a few of them with the GTD bug.
What are your favorite GTD-related Pearls of Wisdom?
If you know who wrote/said it first, please include that credit so I can do so on my posters.
