If you had read my three-part series on Getting Things Done (GTD) and my implementation of it, you would know that I am a GTDer.
David Allen describes the following three stages to become a GTDer:
1. Understanding – You understand the distinct differences in the five phases of mastering workflow. You understand a project versus a next action. You know how to transform what you’ve collected by asking the key processing questions, clarifying what something is, and what you want to do about it.
2. Implementation – You have installed at least the basic gear to support a GTD system, including ubiquitous collection tools, functioning reference systems for your non-actionable information, and seamless buckets with “clean edges” for tracking your projects and next actions.
3. Behavior Change – The five phases of mastering workflow are second nature to you. You have changed the way you think and work and are achieving stress-free productivity on a regular basis. When you “fall off” you know what to do to get “back on.”
The first two stages are relatively simple. The third one is the most difficult.
