9 books everyone should read at least once in their lifetime

by Lachlan Brown | November 24, 2025, 9:27 pm

Every once in a while, a book rearranges you from the inside out.
It shifts your worldview, challenges your assumptions, or simply opens a door you didn’t know existed.
Some books entertain. Some educate. But the rare ones—those truly rare ones—stay with you long after you’ve turned the final page.

These nine books fall into that category.
They span psychology, philosophy, self-growth, fiction, and spirituality—not because I think everyone should study these topics, but because they illuminate universal truths about being human.

If you read each of these at least once in your lifetime, you’ll carry something with you that no one can take away: clarity, depth, and a deeper understanding of yourself and the world.

1. Man’s Search for Meaning — Viktor E. Frankl

Few books hit the human spirit as hard as Frankl’s story of surviving Nazi concentration camps.
But the power of this book isn’t in the suffering—it’s in what Frankl discovered through it:

Humans can endure almost anything if they have a meaning to hold onto.

This book isn’t depressing. It’s the opposite.
It’s a reminder of the strength you didn’t know you had.
It teaches that meaning is not found—it’s created. And that freedom, at its core, is the ability to choose your response, no matter the situation.

I’ve returned to this book many times in moments of self-doubt. It always resets my priorities instantly.

2. The Alchemist — Paulo Coelho

This is one of those rare novels that feels like a fable, a spiritual guide, and a personal conversation all at once.

It’s about following your “Personal Legend,” trusting your intuition, and recognizing that the journey matters more than the destination.

People often underestimate this book because it seems too simple. But like all profound truths, simplicity is the delivery system.
It’s a book that finds you at the exact moment you need it most.

And if you’ve ever been at a crossroads, unsure of what to pursue or who to become, this book shines a gentle light forward.

3. Atomic Habits — James Clear

This is not a “self-help” book—it’s a manual for changing your life through the smallest possible steps.

Clear shows that transformation isn’t about motivation or discipline—it’s about systems.
And if you improve just 1% every day, the compounding effect becomes life-changing.

I especially love how practical the book is. You can read one chapter and immediately take action.
It’s no exaggeration to say that this book has shaped how millions of people build habits that last.

Read it once, implement it forever.

4. Meditations — Marcus Aurelius

If you ever need strength, perspective, or emotional grounding, this book is the ultimate companion.

Written by a Roman emperor privately for himself, Meditations reveals a mind deeply committed to wisdom, humility, and resilience.

It teaches:

  • to stay calm through chaos
  • to detach from ego
  • to focus on what you can control
  • to let go of everything else

This book heavily influenced my own writing and worldview, especially my interest in Buddhist philosophy.
It’s one of those books that gives you a different message each time you return to it.

5. Sapiens: A Brief History of Humankind — Yuval Noah Harari

Few books are as mind-expanding as Sapiens.
Harari takes 300,000 years of human history and distills it into a narrative that explains why we think, act, and live the way we do today.

It’s the kind of book that changes the way you see everything—culture, politics, religion, money, technology, and even human identity.

I remember finishing the book and thinking, “How did I go my whole life without knowing this?”
It’s provocative, challenging, and perspective-shifting in the best possible way.

6. To Kill a Mockingbird — Harper Lee

Some novels become cultural touchstones because they reveal uncomfortable truths with grace and humanity.
This is one of them.

Through a child’s eyes, Harper Lee explores morality, justice, prejudice, compassion, and what it means to do the right thing when it’s the hard thing.

It’s also a reminder of the quiet impact good people can have when they stand firm in their values—something our world still needs.

If you only read one classic in your lifetime, let it be this one.

7. Thinking, Fast and Slow — Daniel Kahneman

If you want to understand the human mind—your own mind—this book is essential.

Nobel Prize–winning psychologist Daniel Kahneman explains the two systems that drive how we think:

  • System 1: fast, automatic, emotional
  • System 2: slow, rational, deliberate

Once you understand these systems, you start noticing how often your brain misleads you.
And you begin making decisions with more clarity and less cognitive bias.

It’s not a light read—but it’s a transformative one.

8. The Four Agreements — Don Miguel Ruiz

This book is short, simple, and genuinely life-changing.

Ruiz presents four principles for living with peace and personal integrity:

  1. Be impeccable with your word.
  2. Don’t take anything personally.
  3. Don’t make assumptions.
  4. Always do your best.

These concepts sound basic, but applied consistently, they remove 90% of the unnecessary drama and suffering from life.

Whenever someone asks me for a book that instantly shifts their mindset, I recommend this.

9. The Power of Now — Eckhart Tolle

If there’s a book that fundamentally changes your relationship with your own mind, it’s this one.

Tolle explains the nature of presence, ego, suffering, and how our thoughts create much of our unhappiness.
It’s not religious—it’s deeply psychological and practical.

For me, this book was a turning point.
It helped me understand that peace doesn’t happen “out there”—it’s cultivated internally by learning to detach from the endless mental chatter we mistake for identity.

It’s a book to read slowly, absorb gently, and revisit whenever life feels overwhelming.

Final thoughts: A good book doesn’t just inform you—it transforms you

The books we read shape who we become.
They help us understand our past, navigate our present, and imagine new futures.
And while there are thousands of brilliant books out there, these nine have earned their place on the list because they expand you—emotionally, intellectually, and spiritually.

Read them slowly.
Let them disturb you a little.
Let them teach you things you didn’t know you needed to learn.

Because the right book at the right time isn’t just information—it’s evolution.

Lachlan Brown is an entrepreneur and co-founder of Brown Brothers Media, a digital publishing network reaching tens of millions of readers monthly. He holds a Graduate Diploma of Psychological Studies from Deakin University, though his real education came afterward: a warehouse job shifting TVs, a stretch of anxiety in his mid-twenties, and the slow discovery that studying the mind is not the same as learning how to live well. He started experimenting with Buddhist principles during breaks at the warehouse and eventually began writing about what he was learning. That writing became Hack Spirit, a widely read personal development site, and his book Hidden Secrets of Buddhism became a bestseller. His work breaks down complex ideas into frameworks people can apply immediately, whether they are navigating a career change, a difficult relationship, or the gap between knowing what to do and actually doing it. Lachlan splits his time between Singapore and Saigon. He writes about high-performance routines, decision-making under pressure, digital innovation, and the intersection of Eastern philosophy with modern life. His perspective comes from having built things from scratch, failed at some of them, and learned that clarity comes from practice, not theory.
