Overview
The ONE Thing by Gary Keller (founder of Keller Williams Realty) and Jay Papasan is a #1 Wall Street Journal bestseller that challenges the myth of multitasking and reveals the power of focused effort.
Core Principle
The book centers on 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 helps you identify the most impactful action in any area of your life.
Key Concepts
The Domino Effect
Success is sequential, not simultaneous. Like dominoes, achieving one goal makes achieving the next one easier. Focus on knocking down the lead domino.
The 80/20 Principle on Steroids
Not all tasks are created equal. Some 20% of your efforts produce 80% of your results. The ONE Thing takes this further—within that 20%, there's usually one thing that matters most.
Six Lies Between You and Success
- Everything matters equally (it doesn't)
- Multitasking works (it doesn't)
- A disciplined life requires willpower (habits matter more)
- A balanced life is best (counterbalancing is better)
- Big is bad (thinking big is essential)
- The opposite of success is failure (it's actually not focusing)
Time Blocking for Your ONE Thing
The book advocates time blocking—dedicating specific hours daily to your ONE Thing:
- Schedule it first, before anything else
- Protect this time fiercely
- Make it non-negotiable
- Build habits around it
Application Areas
Apply The Focusing Question to:
- Spiritual life
- Physical health
- Personal life
- Key relationships
- Job/Career
- Business
- Finances
Impact on Productivity
By focusing on ONE Thing at a time, you:
- Achieve extraordinary results
- Reduce overwhelm and decision fatigue
- Build momentum through sequential success
- Avoid the trap of being busy but not productive
Pricing
