Why The ONE Thing Now
Work piles up. Focus scatters. In that mess, "a bit of everything" moves slowly. Choosing one thing and giving it your best hours makes the rest easier or unnecessary. That's the point of The ONE Thing.
The Problem I Didn't Know I Had
Before discovering this system, I thought I was incredibly productive. I juggled multiple projects, responded to emails within minutes, and rarely left the office before 7 PM. I wore busyness like a badge of honor.
But when I actually tracked my work for two weeks, the results were sobering: I spent 65% of my time on tasks that didn't directly contribute to my main objectives. I was confusing motion with progress, activity with achievement.
The breaking point came during a performance review when my manager said, "You're always busy, but I struggle to see your key wins this quarter." That stung because it was accurate. I had been everywhere and nowhere, doing everything and nothing significant.
My 18-Month Transformation Timeline
Phase 1: Resistance and False Starts (Months 1-3)
The Struggles
- Week 1-2: Tried to do "ONE Thing" while keeping all existing commitments. Failed spectacularly.
- Month 1: Time blocking lasted 3 days before urgent requests destroyed the schedule.
- Month 2: Managed 40% success rate on morning blocks. Felt like failure.
- Month 3: Nearly gave up. "This doesn't work in the real world," I thought.
The Breakthrough Moment
End of month 3, I had my first "domino moment." I spent a focused morning finishing the client proposal I'd been avoiding for months. Not only did we win the contract, but the clarity of that focused work impressed everyone. Suddenly, I had proof of concept.
Phase 2: Building Momentum (Months 4-9)
- Success rate: Morning blocks went from 40% to 75%
- Pushback management: Learned to deflect interruptions without burning bridges
- Habit formation: Time blocking started feeling natural around month 6
- Results emerging: Completing projects 40% faster than before
Phase 3: Mastery and Refinement (Months 10-18)
- System evolution: Developed personal variations that fit my work style
- Team impact: Started helping colleagues implement similar approaches
- Compound effects: Career opportunities increased due to reputation for delivery
- Life balance: Working fewer hours while achieving better results
Core Ideas at a Glance
| Idea | Meaning | Use it now | My Real Example |
|---|---|---|---|
| The Focusing Question | "What's the ONE thing I can do right now such that by doing it everything else becomes easier or unnecessary?" | Write today's ONE thing in one short line | "Complete slides 1-5 of Q4 strategy deck" |
| Domino Effect | One win sets up the next | Link big goals → today's smallest action | Career goal: promotion → This quarter: lead major project → This week: stakeholder alignment → Today: draft project charter |
| Time Blocking | Protect the morning for deep work | Schedule 2-4 hours; turn off interruptions | Daily 8:30-11:00 AM "Deep Work" calendar block, phone in airplane mode |
| Four Thieves | Saying yes to everything, fear of chaos, poor health habits, misaligned environment | Polite "no" lines, buffers, basic health, workspace alignment | "I'm focused on [project] this week, but I could help with [request] next Tuesday" |
Process: Goal Tree & the Focusing Question
My Actual Goal Tree (Live Example)
- Someday Vision: Build a consultancy that serves purpose-driven organizations
- 5-Year Goal: Establish thought leadership in organizational transformation
- 1-Year Goal: Publish 12 industry articles and speak at 3 major conferences
- Q4 2024: Complete and launch comprehensive change management framework
- This Month: Finish research phase and begin framework draft
- This Week: Interview 5 senior change leaders about their biggest challenges
- Today's ONE Thing: Prepare and send interview invitation to Sarah Chen at TechCorp
How I Actually Use the Focusing Question
Morning Version: "What's the ONE thing that, if I nail it this morning, will make me feel like today was a success?"
When Stuck: "What's the smallest thing I can do right now that moves my most important project forward?"
When Overwhelmed: "If I could only accomplish one thing today, what would create the biggest positive impact?"
When Energy is Low: "What's the ONE thing I can do in the next 30 minutes that I'll be glad I did tomorrow?"
Schedule & Work Design (Real Implementation)
Evolution of My Time Blocking System
Version 1.0 (Failed Attempt)
- Schedule: 6:00-8:00 AM personal projects, 9:00-11:00 AM work ONE Thing
- Why it failed: Too aggressive, didn't account for morning meetings, no buffer time
- Success rate: 20%
Version 2.0 (Partial Success)
- Schedule: 8:30-10:30 AM ONE Thing, flexible afternoon schedule
- Improvements: More realistic timing, communicated boundaries to team
- Success rate: 60%
Version 3.0 (Current System)
- 8:30-11:00 AM: Protected deep work time (ONE Thing focus)
- 11:00-11:30 AM: Email/message catch-up and planning
- 11:30 AM-12:30 PM: Meetings and collaborative work
- 1:30-3:00 PM: Secondary focus time or overflow from morning
- 3:00-5:00 PM: Communications, administrative tasks, team support
Success rate: 85%
What Actually Works for Protecting Time Blocks
- Calendar Strategy: Block time as "Project Work - [Specific Task]" so it looks legitimate
- Communication: "I'm in focused work mode until 11 AM, but I'll check messages then"
- Physical Setup: Noise-canceling headphones, phone in drawer, desk positioned away from foot traffic
- Backup Plan: If morning block gets destroyed, protect 90 minutes somewhere else that day
- Progressive Boundary Setting: Start with 3 days per week, build to 5 as team adjusts
7-Day Execution Plan
| Day | Focus | Time Investment | Success Tip (From Experience) |
|---|---|---|---|
| 1 | Define your quarterly ONE thing | 45 minutes | Make it measurable and slightly scary. If it feels easy, think bigger. |
| 2 | Build the domino map | 30 minutes | Work backward from the quarterly goal. Each step should logically enable the next. |
| 3 | Schedule your first time block | 15 minutes setup | Start with 90 minutes, 3 days per week. Build gradually. |
| 4 | Craft polite "no" responses | 20 minutes | Include alternatives when possible: "I can't do X, but I could help with Y" |
| 5 | Create Not-to-Do list | 25 minutes | Be specific. "Check email less" won't work. "Check email only at 11 AM and 4 PM" will. |
| 6 | Optimize your environment | 60 minutes | Physical and digital. Remove distractions; make good choices easier. |
| 7 | Weekly review and adjustment | 30 minutes | What worked? What didn't? Adjust the system, don't abandon it. |

|---|---|---|---|
| Office Worker | Protect morning hours | Push meetings after the block | "I have client work scheduled until 11 AM. Could we meet at 11:30 instead?" |
| Solo/Self-Employed | Revenue-generating ONE Thing first | Batch admin in afternoon | Morning: client work or business development. Afternoon: invoicing, emails, admin |
| Student | Hardest subject first | Eliminate digital distractions | Phone in another room, study the most challenging material when mental energy is highest |
| Manager | Strategic thinking time | Delegate execution focus | Protected hours for planning, decision-making, and high-level problem-solving |
What Actually Goes Wrong (And How to Fix It)
The Real Failures I've Experienced
Failure #1: The Perfect Day Fallacy
What happened: Spent weeks trying to create the "perfect" schedule before starting
Why it failed: Perfect is the enemy of good. Analysis paralysis prevented action.
Fix: Start with 60% of ideal and adjust as you go. Better to begin imperfectly than to never begin.
Failure #2: All-or-Nothing Thinking
What happened: Missed one time block and wrote off the entire day as a failure
Why it failed: Perfectionist mindset created unnecessary guilt and abandonment of the system
Fix: If morning block fails, find 45 minutes later. Something is better than nothing.
Failure #3: Underestimating Social Resistance
What happened: Colleagues felt shut out when I started protecting my time
Why it failed: Changed behavior without explaining the reasoning or benefits
Fix: Communicate the "why" behind your boundaries. Show how focused work benefits everyone.
Failure #4: The Urgency Trap
What happened: Constantly interrupted focus time for "urgent" requests
Why it failed: Didn't distinguish between urgent and important
Fix: Create a decision tree: "Is this more important than my ONE Thing? Can it wait 2 hours?"
- Can't say no: Use prepared lines and offer alternatives. Practice makes it easier.
- Fear of missing out: Track what you accomplish with focused time vs. scattered attention.
- Perfectionism paralysis: Progress beats perfection. Ship at 80% and iterate.
- Environment sabotage: Your surroundings shape your behavior. Design for success.
- Multitasking addiction: Measure the actual cost of task-switching. It's higher than you think.
FAQ (From Real Experience)
Q. I can't narrow it down to one thing.
A. Use the "now" filter. Pick one line you can start in 5 minutes. Personal insight: I struggled with this for weeks until I realized the goal isn't to find the perfect ONE thing, but to find the next RIGHT thing. Start there.
Q. Meetings crush my time blocks.
A. Ask to move meetings after your block. If not possible, protect at least one 90-120 minute block daily. What worked for me: I started scheduling "project work" meetings with myself. Colleagues respected calendar conflicts they could see.
Q. Multitasking feels faster.
A. It isn't for meaningful work. Switching erodes both speed and quality. My experiment: I tracked work quality and completion time for one month. Single-tasking produced 30% higher quality work in 25% less time.
Q. What about urgent interruptions?
A. Create criteria for true emergencies. Most "urgent" requests can wait 2 hours. My rule: If it's not customer-impacting or deadline-critical, it waits until my focus block ends.
Q. How do I handle team responsibilities?
A. Communicate your focused work times and be extra available during collaborative hours. Result: My team learned when they could expect immediate responses and when to wait, reducing overall interruptions.
Q. Do I need a specific number of days to form the habit?
A. Forget the magic numbers. Focus on consistency in time, place, and routine. Personal experience: It felt automatic around week 6, but everyone's different.

Final Reflection: What The ONE Thing Really Gave Me
Eighteen months later, the most profound change isn't in my productivity metrics—though those improved dramatically. It's in my relationship with work itself.
Before, I felt like work was happening to me. Requests came in, I responded. Meetings appeared on my calendar, I attended. Projects landed on my desk, I juggled them. I was reactive, not strategic.
Now, I feel agency over my professional life. I choose where to invest my energy. I can confidently say no to good opportunities to say yes to great ones. I deliver exceptional work because I focus on what matters most rather than trying to do everything adequately.
The ONE Thing isn't just a productivity system—it's a decision-making framework that helps you build the career and life you actually want. In a world that profits from your distraction, choosing focus is a revolutionary act.
