After all the capturing, organizing, and reviewing, it's time for what truly matters—getting things done. The Engage phase is where your GTD system empowers you to make confident decisions about what to work on and to engage with your tasks with focus, clarity, and purpose.
What is Engaging?
Engaging is the action phase of GTD, where you actually do the work. With a trusted system in place, you can now make informed choices about what to work on and engage fully with your tasks without the nagging feeling that you should be doing something else.
The goal of the Engage phase is to:
- Choose the most appropriate actions for your current context
- Focus completely on the task at hand
- Work without mental distractions
- Respond appropriately to what's in front of you
Mind Like Water
David Allen uses the metaphor of "mind like water" from martial arts to describe the ideal state for engagement. When you throw a pebble into a pool of water, the water responds with perfect appropriateness to the force and mass of the input, then returns to calm.
With GTD, you can achieve this state—responding to what's in front of you without overreacting or underreacting, then returning to a state of calm readiness.
The Three-Fold Model for Evaluating Daily Work
When deciding what to work on at any moment, David Allen suggests considering three essential factors:
1. Context
What can you do where you are, with the tools and resources you have available?
- Physical location (office, home, store)
- Tools available (computer, phone, specific software)
- People present (colleagues, clients, family)
- Energy level and mental state
2. Time Available
How much time do you have before your next commitment?
- Short blocks (5-15 minutes) are good for quick tasks and calls
- Medium blocks (30-60 minutes) work for many routine tasks
- Longer blocks (2+ hours) are best for deep work and creative projects
3. Energy Available
What is your current energy and focus level?
- High energy/focus: Complex problem-solving, creative work, learning
- Medium energy/focus: Routine tasks, communications, planning
- Low energy/focus: Administrative tasks, organization, simple reviews
Adding the Fourth Criteria: Priority
Beyond the three-fold model, there's a fourth criteria to consider:
4. Priority
Given the constraints of context, time, and energy, what's the most important thing to do right now?
Consider factors such as:
- Deadlines and time sensitivity
- Impact on goals and projects
- Dependencies (what's blocking other work)
- Opportunities that may not be available later
- Personal and professional values
Strategies for Effective Engagement
Single-Tasking
Focus on one task at a time for better efficiency, quality, and mental presence.
- Eliminate distractions before starting work
- Use time-blocking techniques (like Pomodoro)
- Close unnecessary tabs, apps, and notifications
- Create a dedicated workspace when possible
The Two-Minute Rule
If a task will take less than two minutes, do it immediately rather than tracking it.
- Quick emails and messages
- Simple decisions and permissions
- Brief organizational tasks
- Small administrative duties
Batching Similar Tasks
Group similar tasks to maintain mental context and reduce switching costs.
- Process all emails in one session
- Make all phone calls together
- Handle paperwork and forms in a batch
- Do all your errands on one trip
Engagement Mindset
When you trust that everything else is captured in your system, you can engage with the current task with full attention and what Allen calls "mind like water" - an appropriate response to what's in front of you without overreacting or underreacting.
This state of focused engagement allows you to be fully present with whatever you're doing, which not only produces better results but also reduces stress and increases satisfaction.

The GTD Mastery Journey
Mastering GTD is not a one-time achievement but an ongoing practice that evolves as your needs and circumstances change:
Getting Started
Implementing the basic system components: capture tools, inbox processing, organizing next actions, and creating a basic review habit. Focus on building the foundational elements before worrying about optimization.
Developing Habits
Establishing regular patterns of capture, clarification, organization, and review. This is where GTD begins to become second nature and where the real benefits of mental clarity start to emerge.
Integrating
Making GTD a natural part of your workflow where it stops feeling like a separate "system" and becomes just how you work. At this stage, your trusted system enables greater focus and stress reduction.
Mastering
Fine-tuning your system to your specific needs and style. At this level, you intuitively know how to adjust your approach based on changing circumstances and can achieve "mind like water" consistently.
"Remember that perfect implementation isn't the goal—having a system that works for you is what matters. Start where you are, improve incrementally, and enjoy the benefits of increased clarity and control."
Putting It All Together
You've now learned all five phases of GTD: Capture, Clarify, Organize, Reflect, and Engage. When implemented together, these create a powerful system that helps you manage your work and life more effectively and with less stress.
To keep your GTD practice strong, consider these final tips:
- Prioritize your Weekly Review — it's the cornerstone of an effective GTD practice
- Keep your system as simple as possible while still serving your needs
- Adjust your approach as your circumstances change
- Focus on progress, not perfection
- Use the right tools for your style and preferences
