About the author and the book
Gary Keller is the co-founder of the real estate company Keller Williams, and Jay Papasan is a writer and editor. The ONE Thing: The Surprisingly Simple Truth Behind Extraordinary Results, published in 2013, mixes productivity advice, stories and business examples around one central idea: go small.
The six lies about success
| The lie | The truth the book offers |
|---|---|
| Everything matters equally | A few things matter far more than the rest |
| Multitasking | It splits attention and lowers quality |
| A disciplined life | You need just enough discipline to build the right habits |
| Willpower is always on will-call | Willpower runs out, so do the key task first |
| A balanced life | Aim for counterbalance, not a perfect split of time |
| Big is bad | Thinking big sets your direction and your potential |
5 ideas worth remembering
1. The focusing question
Keller proposes one question to use for your life, your work and each day: what is the one thing that makes everything else easier or unnecessary? The answer should be specific to your goal and time frame.
2. The domino effect
A small domino can knock down one about 50% bigger. Likewise, one well-chosen action can start a chain reaction that leads to far larger results.
3. Go small
Instead of trying to do everything, narrow your focus until you find the lead domino. Success is sequential, not simultaneous.
4. Time blocking
The authors suggest blocking several hours early each day for your ONE Thing and protecting that time from interruptions.
5. Goal setting to the now
Start from a big goal, then work backward to what you must do this year, this month, this week and today.
Strengths and limits

- Short chapters and clear examples.
Where it falls short
- The core message is repeated many times and could be shorter.
- "One thing" is a simplification when real jobs demand several priorities.
- Some of the "lies" are stated more strongly than the research supports, and many examples come from business success stories.
Who should read it?
Who should read it: people who feel scattered, and leaders who need to set priorities. Who may skip it: readers who already use a strong prioritization system, or who want a detailed time-management method.
