David Allen's Getting Things Done is a masterful work that turns disorganized and stressed-out people (like myself) into productive, hardworking, and efficient workers. His GTD System focuses on transforming the way individuals handle their incoming tasks and obligations so that things get done in an organized and concise manner, freeing the mind up to do the creative work that it was made to do.
Getting Things Done is composed of three main parts. Part one is titled: "The Art of Getting Things Done." In this section, David Allen does an excellent job illustrating every day (shoddy) work habits that many exercises and explains what an effective work habit ought to be.
In part two, titled: "Practicing Stress-Free PRoductivity," Allen takes his audience through a step-by-step guide to improving workflow. Allen starts by getting his audience to "take control" of their current workspace, setting it up to be organized and efficient, and then goes on to lead his audience through several exercises in which the reader evaluates their current work habits. Some examples of these exercises are: practicing making effective "next action" decisions and practicing the habit of a "weekly review."
In part three, titled "The Power of Key Principles," Allen builds off of the basis set in the previous two sections by providing his audience with principles to lie and die by. These principles are intended to keep our minds proactive, always focused on the next step. By doing this, we will ultimately free our minds up to think creatively.
All in all, David Allen's Getting THings DOne has made a tremendous impact on my life. Concepts like using capturing tools and focusing on next actions have improved my productivity significantly. I cannot recommend this work enough. If you are someone who struggles with getting things done, this book is a necessary read.
