Getting Things Done, commonly abbreviated as GTD, is an action management method, and the title of a book by David Allen.
GTD rests on the principle that a person needs to move tasks out of the mind by recording them somewhere. That way, the mind is freed from the job of remembering everything that needs to be done, and can concentrate on actually performing those tasks.
GTD embodies an easy, step-by-step and highly efficient method for achieving this relaxed, productive state. It includes:
1. Describe in a single sentence the intended successful outcome for the problem or situation
2. Write down the very next physical action required to move the situation forward, e.g., "Make oil change appointment", vs. "Get oil changed"
1. Horizontal maintains coherence across all activities in which you are involved
2. Vertical manages thinking up and down the track of individual topics and projects
