Organize is the hinge of the GTD CORE model (Capture/Clarify, Organize, Reflect and Engage). It involves developing an "external brain" where you park all of your next actions and projects so you can trust that you will interact with them appropriately and not let things fall through the cracks. Several software tools and apps have been developed as tools to support this Organize function. Which one did you pick? How is it working for you?
