NOT time management
I'm grateful for this latest one-page description of what GTD actually is.
I know what it is because I'm using it but I struggle to explain to others, whom I believe could benefit from it, what makes it different to any particular time-management system. I became very turned off by time management; all too often time management systems are just another way to cram more in and burn yourself out. Because of this I've been tending to recommend GTD by telling others what it's not.
GTD is a completely different because of the peace of mind and improvement of quality of life it brings. This new description will help me recommend it to others.
