The document discusses Getting Things Done (GTD), a productivity system created by David Allen. GTD is a framework for managing tasks and projects using a process of collecting, processing, organizing and reviewing information, and taking action. It involves capturing all commitments and tasks, clarifying actions, and organizing information into lists of next actions, projects and some day/maybes. The goal is to reduce stress and focus on the most important tasks. The document provides an overview of the GTD process and recommends apps and resources for implementing GTD.
