I could write my own enthusiastic review of Michael Hyatt’s Full Focus Planner, a planning/diary tool developed from his limpidly clear thinking on how to organise your life to achieve the things which are important (rather than trying to cram even more into the limited time you have)—but Chris Green has done such a good job that I refer you to Chris’ excellent review of the (new) third edition. I’m loving using this tool alongside the digital  Nozbe as my project software.
