Getting Things Done

Allen's system for keeping commitments out of your head and in a set of lists you trust. The workflow moves through capturing everything that has your attention, clarifying what each item actually is, organising the results into project and next action lists, reviewing them weekly, and then engaging with confidence about what you have chosen not to do. The middle of the book is a step by step implementation, including the physical setup, the two minute rule, and the natural planning model for anything larger than a single action. The final part explains why the method works, drawing on the cognitive cost of unfinished commitments. The 2015 revision updates the tooling references for digital work while leaving the method itself intact.
