Every year, we promise ourselves we’ll exercise more, earn more money, study harder, nurture our relationships, and take on new challenges. Everything feels important. Nothing seems optional. However, Gary W. Keller and Jay Papasan’s book, The ONE Thing, asks the exact opposite: Is everything really that important?

The book argues that the belief “everything is important” is one of the most dangerous mindsets we can have. In fact, it’s not just slightly wrong—it’s fundamentally flawed. When everything is important, priorities disappear. And when priorities disappear, energy becomes scattered. Scattered energy produces average results. We end up living busy lives without achieving anything truly meaningful. Success is rarely the result of doing many things well at the same time. More often, it comes from doing one most important thing exceptionally well.

We often compare life to a marathon—a long game where we must pace ourselves. While that’s true in a sense, the book offers a more practical perspective: life is a “short-term sprint until a habit is formed.” It takes an average of 66 days for a new behavior to become a habit. If you focus on and repeat one thing for 66 days, it stops being a task fueled by willpower and starts being an automated system. Ultimately, what changes your life is not a burst of motivation, but a system that keeps running.

So, why do we struggle to focus on just one thing? The reason is simple: everything else look appealing. Other things seem more important or urgent, and we’re hit with the anxiety of missing out. So we grab at everything. The problem is that every “extra” thing we hold onto steals a piece of our focus. When energy is divided, results are divided. And once again, we’re left wondering, “Why haven’t I made any real progress?”

There’s a famous story about Warren Buffett that illustrates this perfectly. When a young man asked for the secret to success, Buffett told him to list 25 goals he wanted to achieve. Then, he told him to circle the top five. When the young man said he’d work on the other 20 whenever he had free time, Buffett stopped him. He said those 20 are now your “Avoid-At-All-Costs List.” Success with the top five is already hard enough. True focus is not about adding more. It’s about eliminating what doesn’t matter most.

The core question of the book is this: “What is the ONE thing I can do such that by doing it, everything else will be easier or unnecessary?” This is a strategic question. It’s not just about finding something “important”; it’s about finding the leverage point that lowers the difficulty of everything else. In business, it might be a flagship product; for an individual, it might be health; for an investor, it might be a specific skill set.

Bill Gates once said that people overestimate what they can do in one year and underestimate what they can do in ten. We try to flip our lives upside down in 12 months, list 20 goals, and burn out within weeks. We lose our long-term consistency in the process. But if you repeat one thing for ten years, the story changes completely. It may look slow at first, but the power of compounding is staggering.

Think of it as conquering one domain per year. One year, your “One Thing” might be health. If you fully systemize your fitness that year, you don’t have to make it your top priority the next—the system is already running. The next year might be investing, and the year after that, business expansion. By stacking these wins one by one, you’ll find yourself on a completely different level in five or ten years.

Now the question returns to you. What is the ONE thing you must accomplish in 2026? If you achieve it, will other things become easier? Are you ready to commit to it for 66 days without distraction? Of course, focusing on just one thing can feel risky. What if it’s the wrong choice? What if you miss other opportunities? But is it truly safer to remain scattered, never fully committing to anything?

Perhaps we fear choosing more than we fear failing. Yet one truth remains clear:
no risk = no story.
