Practical Takeaways from the book 'The ONE Thing' by Gary Keller and Jay Papasan
The central theme of The ONE Thing by Gary Keller and Jay Papasan revolves around a pivotal question:
“What is the ONE Thing I can do such that by doing it, everything else will be easier or unnecessary?”
Asking this focusing question paves the way for deliberate and meaningful answers.
By consistently reflecting on this, you can streamline your efforts, minimise distractions, and ensure your actions are purposeful.
I first came across The ONE Thing through a recommendation in a Facebook group while searching for a book to kickstart the new year. Now, on my third read, I felt compelled to share the insights that resonated most with me.
Note: This isn't a comprehensive summary of the book. For those interested, check this link for a concise summary.

Here are my five key takeaways from The One Thing:
1. The Myth of Multitasking
In The One Thing, Gary Keller and Jay Papasan debunk the widespread belief that multitasking is an efficient way to get more done. They argue that our brains aren't designed to handle multiple tasks simultaneously. Instead, when we think we're multitasking, we're actually just switching rapidly between tasks, which can lead to mistakes and reduced productivity.
Everyday Examples Highlighting This Myth:
- Driving While Using a Mobile Device: The divided attention significantly increases the risk of accidents, which is why it's illegal in many places.
- Listening to Music While Walking: Many of us enjoy listening to music during our walks. However, when approaching busy intersections or navigating through crowded areas, it's common to lower the volume or remove earbuds to stay alert to our surroundings. This adjustment helps us focus on potential hazards and ensures safety. This behavior underscores that even during routine activities like walking, our brains prioritise safety over entertainment, highlighting the limitations of multitasking.
- Cooking While Engaging in a Conversation: Chatting while cooking is a familiar scenario. However, when reaching a critical step in a recipe, many of us instinctively pause the conversation to concentrate on the task at hand. Failing to do so can lead to missed steps or incorrect measurements, affecting the dish's outcome. This tendency to single-task during crucial moments in the kitchen illustrates our inherent need to focus on one task to ensure quality results..
- Participating in Virtual Meetings While Checking Emails: It's common to glance at emails during online meetings, but this often means missing out on key discussion points, leading to misunderstandings or extra work later.
- Watching TV While Scrolling Through Social Media: Ever found yourself watching a show and scrolling through your phone at the same time, only to realise you've lost track of the plot? This common scenario shows how multitasking can diminish our engagement and enjoyment of activities.
To do two things at once is to do neither.

2. Live by Priority
The book emphasises on the term priority, as opposed to its pluralised version now, priorities– suggesting multiple tasks matter equally. Originally, priority meant focusing on the most important thing. Your priority is your ONE thing. Living by priority involves identifying your ONE most important task– the one that aligns with your long-term goals– and making consistent and focused effort toward it. This means each step you take each day leads you closer to where you want to be tomorrow.
The one who wants to build high towers must linger long at the foundation.
~ Anton Bruckner
3. The Success Habit
Building a new habit doesn't happen overnight. Research states that it takes about 66 days to form a habit. This process involves making small, consistent actions daily until they become second nature. By regularly asking the focusing question and directing your willpower and discipline on forming one meaningful habit at a time, you set the foundation for sustained success. Over time, these habits compound, leading to significant personal and professional growth.
We are what we repeatedly do. Excellence, then, is not an act but a habit.
~ Aristotle
4. Follow the Path of Mastery
This is the first commitment to your ONE thing. Mastery is a continuous journey rather than a final destination; it’s about commiting to continuous learning and improvement in your chosen field. By aligning this pursuit with your ONE thing, you ensure that your efforts are focused and purposeful, guiding you steadily toward your long-term goals.

~ Bruce Lee
5. The Health Habit
One of the key obstacles to achieving extraordinary results, as highlighted in The ONE Thing, is poor health habits. While we often hear that anything is possible if we set our minds to it, the state of our health significantly influences our capacity to turn those thoughts into actions. Neglecting our well-being can sap our energy and focus, making it challenging to pursue our goals effectively.
Incorporating simple, healthy habits into our daily routine can make a substantial difference. Physically, this includes regular exercise, balanced nutrition, and adequate sleep are foundational to maintaining the energy and mental clarity needed for productivity. Setting realistic wellness goals and creating a supportive environment can further enhance our ability to stick to these habits. By prioritising our health, we equip ourselves with the vitality required to tackle our most important tasks and move closer to our aspirations.Remember, taking care of your health isn't just about adding years to your life; it's about adding life to your years. In summary, maintaining good health is foundational to achieving your goals, as it provides the necessary energy and focus to turn your aspirations into reality.
I'll revisit this book next year to track my goals and monitor my progress. The insights I've shared—debunking the myth of multitasking, emphasising the importance of prioritisation, cultivating success habits, committing to mastery, and maintaining health—have guided my personal and professional endeavours this year. I hope these takeaways inspire you to identify your ONE thing and pursue it with unwavering focus and dedication.
