Getting Things Done by David Allen is the most influential productivity book I know of. When I saw Allen speak at the Growth Summit in 2009, I saw first-hand what “mind like water” could mean. He was the most relaxed, present speaker I’ve ever seen. If I could sum up his work in just one concept, it would be the idea of readiness. We have all kinds of different tasks on our to-do lists. Which types are best done at which time of day and at which location. Some things I can do in line at the post office, others need a solid, uninterrupted hour in front of my computer, with an internet connection. The other part of readiness that’s so important is that of “Next Action.” If your to do list says “new tires for car” there is friction in the mind because that’s not an action, which means your brain can’t let it go until the time is right. What is the next action? Is it “google tire place phone number” or “call tire place to make appointment” or “ask spouse to call tire place for appointment?” What’s your next action on that important project?
