In "The One Thing," Gary Keller and co-author Jay Papasan explain how to determine your goal or life purpose, and then focus intensely on getting there while avoiding pitfalls such as multitasking, relying on an unprioritized to-do list, thinking too small, misunderstanding willpower and discipline, and neglecting your personal life.
The ONE Thing by Gary Keller and Jay Papasan emphasizes focusing on the single most important task in any area of your life to achieve extraordinary results.
"One thing" stands for prioritizing a single task and focusing on something specific. The philosophy is that by doing one thing at a time with full focus, you can achieve extraordinary results.
The central tool of the method is what Keller calls "the focusing question":
"What's the ONE THING I can do such that by doing it everything else will be easier or unnecessary?"
This question should be asked:
- For your life: What's my ONE Thing?
- For this year: What's my ONE Thing this year?
- For this month: What's my ONE Thing this month?
- For this week: What's my ONE Thing this week?
- For today: What's my ONE Thing today?
- Right now: What's my ONE Thing right now?
There are three components to implementing your One Thing and achieving exceptional results:
Your big One Thing is your purpose—your ultimate goal or life direction.
Questions to identify purpose:
- What do I want my life to be about?
- What matters most to me?
- What legacy do I want to leave?
Your small One Thing is your priority—what you do today to achieve your purpose.
Questions to identify priority:
- What's the one thing I can do right now?
- What makes the biggest impact?
- What aligns with my purpose?
How you protect time and energy to work on your priority.
Key principle: Schedule your One Thing and protect that time fiercely.
The key to productivity is scheduling or blocking time on your calendar to focus on your priority and treating that time as sacrosanct.
Block at least four consecutive hours of uninterrupted time to focus on your ONE thing each day.
Best practices:
- Schedule it at your peak energy time
- Treat it as an unmovable appointment
- Batch all other activities outside this block
- Turn off all notifications during this time
- Communicate boundaries to others
Gary Keller claims that success is created by doing the One Thing at a time, like falling dominos, to compound to produce extraordinary results.
The concept:
- Each focused effort is like tipping a domino
- That domino knocks down the next
- Momentum builds progressively
- Small actions compound into big results
- One thing leads naturally to the next
Truth: Not all tasks are created equal. Some matter vastly more than others.
Truth: Multitasking is actually task-switching, which reduces productivity and quality.
Truth: You don't need discipline for everything, just enough to build the right habits.
Truth: Willpower is like a battery that depletes. Do your ONE Thing when willpower is highest.
Truth: Extraordinary results require focused imbalance. Work-life balance comes from counterbalancing focus with rest.
Truth: Thinking small limits possibilities. Think big, focus small.
Use the focusing question for different time horizons:
- Life ONE Thing (purpose)
- 5-year ONE Thing
- This year's ONE Thing
- This month's ONE Thing
- This week's ONE Thing
- Today's ONE Thing
- Right now's ONE Thing
- Block 4 hours daily (minimum)
- Schedule during peak energy
- Put it on your calendar first
- Protect this time ruthlessly
- Start with 66 days of consistency
- Use implementation intentions
- Track your progress
- Celebrate small wins
Protect your ONE Thing by:
- Declining non-essential meetings
- Delegating other tasks
- Automating what you can

Solution: Use the focusing question to identify which ONE thing makes others easier or unnecessary.
Solution: Communicate boundaries, block calendar, use "do not disturb" mode.
Solution: Remember that by making your ONE thing work, you're making everything else easier.
Solution: It's okay to adjust. Start with your best guess and refine.
