Join David Allen for a fascinating, wide-ranging conversation with Daniel Levitin, author of The Organized Mind. Daniel is a professor of psychology, a cognitive scientist, a musician, an entrepreneur, and more. He brings recent cognitive research to bear on GTD, validating obectively what GTD users know subjectively -- that getting things off your mind frees your mind for more creative and productive thinking. David and Daniel discuss why the brain pays attention to some things and ignores others, the limits of short-term memory versus long-term memory, and why the Mind Sweep is not just a good idea, but a critical part of dealing with our modern lives.
