About Greg McKeown

Greg McKeown is the bestselling author behind Essentialism: The Disciplined Pursuit of Less and Effortless: Make It Easier to Do What Matters Most. Together, his books have sold over 3 million copies, been translated into 40 languages, and established him as one of today’s leading voices on focus, simplicity, and impact. A sought-after public speaker, McKeown has shared his insights with audiences in more than 45 countries and with organizations ranging from Apple, Amazon, and Google to Nike, Microsoft, X, and even the U.S. Navy SEALs. He holds a master’s degree from Stanford University and is pursuing doctoral research at the University of Cambridge on the science of getting the right things done – together. Beyond his work, McKeown and his wife, Anna, are raising four children, a living reminder of his philosophy that what matters most deserves our best attention.

About The Book

“The way of the Essentialist means living by design, not by default. Instead of making choices reactively, the Essentialist deliberately distinguishes the vital few from the trivial many, eliminates the nonessentials, and then removes obstacles so the essential things have clear, smooth passage. In other words, Essentialism is a disciplined, systematic approach for determining where our highest point of contribution lies, then making execution of those things almost effortless. […]

This book will show you how to live a life true to yourself, not the life others expect from you. It will teach you a method for being more efficient, productive, and effective in both personal and professional realms. It will teach you a systematic way to discern what is important, eliminate what is not, and make doing the essential as effortless as possible. In short, it will teach you how to apply the disciplined pursuit of less to every area of your life.”

This book found me at exactly the right time. As a working mum of three, I was juggling projects, school runs, endless life admin, meal prep, and a half-finished home renovation – all while wondering why I felt constantly busy but rarely productive. Essentialism by Greg McKeown was the wake-up call I didn’t know I needed – a reminder to pause, step back, and redesign my life around what truly matters.

If you’ve ever felt like you’re drowning in to-dos, information overload, or the pressure to “do it all,” this book will feel like a breath of fresh air.

McKeown, a leadership consultant who’s worked with Apple, Google, and Facebook, introduces what he calls the disciplined pursuit of less. At the core of his approach is not getting more done, but getting the right things done. It’s a mindset shift: replacing “I have to do everything” with “What’s the most essential thing I can do right now?”

By learning to say no more often and focusing only on what’s truly essential, we regain control of our time, energy, and choices, and eventually create space for a life that’s not just full, but meaningful.

I loved this book and can’t wait to share the insights that helped me simplify, refocus, and breathe again.

Let’s dive in.

Key Insights:

What’s Your Priority?

“The word priority came into the English language in the 1400s. It was singular. It meant the very first or prior thing. It stayed singular for the next five hundred years. Only in the 1900s did we pluralize the term and start talking about priorities. Illogically, we reasoned that by changing the word we could bend reality.”

Translation: You don’t get five “first” things. There’s one. That’s the point.

This is where Essentialism splits from the default way most of us live. Essentialists focus their energy on one priority. Nonessentialists spray their energy across a million tasks and wonder why they’re exhausted and nothing really moves.

McKeown’s message here is painfully simple: There is no such thing as priorities. You can’t have it all. Period.

So here’s your challenge. Grab a journal and answer:

“What would happen if we could figure out the one thing you could do that would make the highest contribution?”

Write it down. Circle it. That’s your compass.

Because here’s the harsh truth:

“If you don’t prioritize your life, someone else will.”

And if you’re still not sure, make the ability to prioritize your highest priority. 

Three Realities of the Essentialist Thinking

1. Individual choice: We can choose how to spend our energy and time. Without choice, there is no point in talking about trade-offs.

2. The prevalence of noise: Almost everything is noise, and a very few things are exceptionally valuable. This is the justification for taking time to figure out what is most important. Because some things are so much more important, the effort in finding those things is worth it.

3. The reality of trade-offs: We can’t have it all or do it all. If we could, there would be no reason to evaluate or eliminate options. Once we accept the reality of trade-offs we stop asking, “How can I make it all work?” and start asking the more honest question “Which problem do I want to solve?” 

Only when we understand these realities can we begin to think like an Essentialist.”

This is the foundation. Once you digest these three truths, you can actually start doing the work (“the method”): explore → eliminate → execute.

In simple terms: 

1. Figure out what matters.

2. Cut what doesn’t.

3. Then make the important stuff as effortless as possible.

These shifts also free us from cultural expectations: the hustling, the endless productivity checklists, and the pressure to be everything to everyone. When we choose fewer, better things, we reclaim our energy for work that actually matters.

A personal example: I’ve always wanted to run a marathon. Great dream, but honestly, it’s not the priority right now. Staying fit enough to chase three children around the house is. So I run short distances a few times a week. It’s a nod to the 1% rule – slow, steady progress toward future goals without pretending everything is urgent right now.

This connects to a realization I had on my 35th birthday: you can have it all – just not at the same time. Priorities evolve. What matters deeply today might shift in six months or ten years, and that’s normal. The key is to revisit those priorities often and adjust intentionally, rather than drifting by default.

Which Problem Do You Want?

“It is easy to see why it’s so tempting to deny the reality of trade-offs. After all, by definition, a trade-off involves two things we want. Do you want more pay or more vacation time? Do you want to finish this next e-mail or be on time to your meeting? Do you want it done faster or better? Obviously, when faced with the choice between two things we want, the preferred answer is yes to both. But as much as we’d like to, we simply cannot have it all.

A Nonessentialist approaches every trade-off by asking, “How can I do both?” Essentialists ask the tougher but ultimately more liberating question, “Which problem do I want?” An Essentialist makes trade-offs deliberately. She acts for herself rather than waiting to be acted upon. As economist Thomas Sowell wrote: “There are no solutions. There are only trade-offs.””

This truth bomb hits hard.

We all want the fantasy version of life where we can have every good thing at once – the perfect career, perfect partner, perfect kids, perfect body, and the free time to contemplate all of that perfection. Sadly, that universe exists only on Instagram and maybe in the marketing department of Lululemon.

Real life is full of trade-offs. And nowhere is that clearer than in parenting.

Every decision has a cost, and pretending otherwise is how we end up exhausted, resentful, or confused about why things feel off. When you choose one thing, you un-choose another. Whether you admit it or not.

So the real question isn’t “How do I get everything?” It’s: Which problem do I want?

Because both paths come with problems.

Full-time working mom vs. stay-at-home mom?

Do I want the challenge of building a big career and trusting others to help raise my kids?

Or do I want the challenge of hitting pause professionally to be more present at home?

Both paths have benefits. Both have consequences. Neither is “right.” Both are a problem — just different ones.

Give the kids phones so I can finally drink a coffee in silence and watch my favourite show in peace?

Or keep the phones away and deal with the boredom, chaos, and eventual creativity that comes from it?

Again – different problems.

The point is: we always have a choice. But we forget that. We act like life forces our hand. It doesn’t.

Essentialism teaches that freedom isn’t about avoiding problems – it’s about choosing the problems that align with what matters most to you.

So ask yourself: Which problem do I want? And then choose on purpose.

Create Space To Think

“Here’s another paradox for you: the faster and busier things get, the more we need to build thinking time into our schedule. And the noisier things get, the more we need to build quiet reflection spaces in which we can truly focus.

No matter how busy you think you are, you can carve time and space to think out of your workday.”

It sounds counterintuitive, but the busier life gets, the more we need to slow down. When everything is moving fast, our minds get flooded with noise – notifications, meetings, to-dos, expectations. Without intentional space to reflect, we just react, chasing urgency over importance.

High-profile executives do this all the time. They take deliberate time off to think, read, or simply be alone with their thoughts. They understand something most of us forget: clarity doesn’t come from doing more. It comes from thinking more.

This idea isn’t new. It’s echoed in Bored and Brilliant by Manoush Zomorodi and Deep Work by Cal Newport: the real magic happens in focused, uninterrupted thinking. When we carve out space, we notice what actually matters, and can act on it instead of spinning our wheels.

Here’s a practical challenge: Carve out 30 minutes each day to think, reflect, or simply do nothing. No phone, no meetings, no multitasking. Let your mind wander. Let yourself be bored. 

Protect Your Asset

“The best asset we have for making a contribution to the world is ourselves. If we underinvest in ourselves, and by that I mean our minds, our bodies, and our spirits, we damage the very tool we need to make our highest contribution. One of the most common ways people—especially ambitious, successful people—damage this asset is through a lack of sleep.”

It’s simple, but we often ignore it. You can’t pour from an empty cup. Think of the airplane oxygen mask rule: put yours on first, then help others. It’s the same principle for life, work, and parenting.

Investing in yourself isn’t selfish – it’s essential. Eat well. Move. Sleep. Recharge. Your mind, body, and spirit are the tools you need to make a meaningful contribution.

Parents surviving on three hours of sleep and a cold coffee might laugh nervously here. Been there. The truth is, we make trade-offs every day, but some shortcuts cost us more than we realize. When my kids were little, full nights of sleep were a distant dream. That’s when I came across NSDR (Non-Sleep Deep Rest) in Dr Huberman’s podcast. A few minutes of practice had a profound effect on my energy, focus, and overall wellbeing. Small hacks can make a big difference.

And here’s something too often forgotten: play matters. Play is a fuel for creativity, mood, and wellbeing. Make time to laugh, move, and be silly. 

Selective Criteria For Decision Making

Here’s a simple, systematic process you can use to apply selective criteria to opportunities that come your way. First, write down the opportunity. Second, write down a list of three “minimum criteria” the options would need to “pass” in order to be considered. Third, write down a list of three ideal or “extreme criteria” the options would need to “pass” in order to be considered. By definition, if the opportunity doesn’t pass the first set of criteria, the answer is obviously no. But if it also doesn’t pass two of your three extreme criteria, the answer is still no.”

In plain language: filter before you commit.

Instead of reacting to every opportunity or request, take a few minutes to define what actually matters. Start by writing the opportunity down. Then ask:

  • What are the must-have requirements?
  • What are the ideal or “stretch” requirements?

If it doesn’t meet the must-haves, the answer is no. If it misses most of the ideal requirements, the answer is still no.

Yes, the hardest part is figuring out your top criteria, but once you do, decision-making becomes much simpler and far less stressful. 

Separate The Decision From The Relationship

When people ask us to do something, we can confuse the request with our relationship with them. Sometimes they seem so interconnected, we forget that denying the request is not the same as denying the person. Only once we separate the decision from the relationship can we make a clear decision and then separately find the courage and compassion to communicate it.”

This is simple, but profound, and incredibly relevant for parenting, leadership, and life in general. Too often, we feel guilty saying no because we conflate the request with the relationship. We forget: refusing something does not mean rejecting someone.

For example:

  • Saying no to ice cream with rice crispies for breakfast? You’re not denying your child – you’re denying an unreasonable request.
  • Saying no to a teenager wanting a sleepover? Again, not denying them, just the ask.
  • Your partner declining your request to spend the whole summer with your parents? Still not a denial of them, just of the request.

Try this the next time you face a tough decision: separate the relationship from the issue. It makes saying no clearer, kinder, and far less emotionally charged.

McKeown adds another gem about boundaries::

Essentialists, on the other hand, see boundaries as empowering. They recognize that boundaries protect their time from being hijacked and often free them from the burden of having to say no to things that further others’ objectives instead of their own. They know that clear boundaries allow them to proactively eliminate the demands and encumbrances from others that distract them from the true essentials.”

Boundaries aren’t a punishment – they’re a superpower. They protect your time, your energy, and your priorities. 

Clear boundaries = freedom to focus on what really matters. For adults and children alike.

What’s Important Now?

“The ancient Greeks had two words for time. The first was chronos. The second was kairos. The Greek god Chronos was imagined as an elderly, gray-haired man, and his name connotes the literal ticking clock, the chronological time, the kind we measure (and race about trying to use efficiently). Kairos is different. While it is difficult to translate precisely, it refers to time that is opportune, right, different. Chronos is quantitative; kairos is qualitative. The latter is experienced only when we are fully in the moment—when we exist in the now.”

Here’s the mind-bending part: in practical terms, we only ever have now. We can’t control the future. We can learn from the past. We can imagine what’s ahead. But only in the present can we act on what truly matters.

Nonessentialists spend too much time dwelling on yesterday or worrying about tomorrow. They chase their past achievements or future ambitions, and in the process, they miss the present. Life slips by while they’re distracted, unfocused, and not fully there.

Essentialists, on the other hand, tune into the present moment. They live in kairos, not just chronos. They focus on what is truly important right now – not what was or what might be.

This is especially powerful in parenting. While it’s good to have a long-term vision for your child, the most meaningful impact comes from being fully present with the child you have today – not the one you hope they become.

It’s a simple but profound question to ask yourself: What’s important now?

Focus on that. Everything else can wait.

Action Steps For You:

  • Identify Your One Priority. Take a moment to reflect: “What is the one thing I could do right now that would make the biggest difference?” Write it down, circle it, and use it as your compass. Focus on this priority before anything else.
  • Eliminate What’s Not Essential. Say no to tasks, requests, or habits that don’t serve your priority. Clear out distractions, commitments, and noise. Less truly is more – every “yes” to something nonessential steals energy from what really matters.
  • Create a Routine to Focus on What’s Important. Design a daily or weekly rhythm that protects time for your priority. Build space to think, plan, and act deliberately. When it becomes a routine, focusing on what matters most is no longer a struggle – it becomes effortless.

Quotes From The Book

“The way of the Essentialist is the relentless pursuit of less but better. It doesn’t mean occasionally giving a nod to the principle. It means pursuing it in a disciplined way.”

“Essentialism is not about how to get more things done; it’s about how to get the right things done. It doesn’t mean just doing less for the sake of less either. It is about making the wisest possible investment of your time and energy in order to operate at our highest point of contribution by doing only what is essential.”

“We can try to avoid the reality of trade-offs, but we can’t escape them.”

“Essentialists see trade-offs as an inherent part of life, not as an inherently negative part of life. Instead of asking, “What do I have to give up?” they ask, “What do I want to go big on?” The cumulative impact of this small change in thinking can be profound.”

“Play doesn’t just help us to explore what is essential. It is essential in and of itself.”

“If it isn’t a clear yes, then it’s a clear no.”
