Stop forgetting what you read: The art of retaining nonfiction 🧠


If you only read the books that everyone else is reading, you can only think what everyone else is thinking. - Haruki Murakami, Norwegian Wood

Hi Reader,

a few years ago, I finished reading what I thought was one of the most impactful nonfiction books I’d ever come across. I highlighted passages, nodded along to the key insights, and felt inspired to change my habits. But a few months later, when I tried to recall the book’s lessons, my mind went blank. The details that had felt so valuable at the time were gone, leaving only a vague impression of what I’d learned.

Sound familiar? Many of us experience this frustration. Nonfiction books are packed with knowledge, strategies, and life-changing advice, but so much of it slips away if we’re not intentional about how we read and engage with the material.

The truth is, retaining what you read isn’t just about memory—it’s about active engagement. When you approach reading with a purpose and use strategies to connect with the material, you’ll hold on to more of the ideas that matter and be able to apply them when it counts.

The science of forgetting

Have you ever wondered why it’s so hard to recall the details of a book just days or weeks after you’ve finished it? The answer lies in how our brains process and store information.

German psychologist Hermann Ebbinghaus studied this phenomenon over a century ago and introduced the concept of the forgetting curve. His research revealed that, without reinforcement, we forget up to 80% of newly learned information within just a few days. This rapid memory decay happens because our brains prioritize efficiency: they let go of information we don’t actively use to make room for new experiences.

But the problem isn’t just about memory—it’s also about how we approach reading. When we read passively, skimming words or simply consuming ideas without deeper engagement, those ideas are less likely to stick. In contrast, active learning—through questioning, summarizing, or applying what we read—encourages our brains to store information in ways that make it easier to recall later.

The good news? Retention isn’t fixed. It’s a skill you can develop. By understanding how memory works and adopting habits that promote active learning, you can remember more, recall ideas more easily, and truly benefit from the books you read.

While you're reading

How you approach a book as you’re reading can make all the difference in what you retain. Active engagement is the key. Here’s how to do it:

  • Highlight key ideas (but keep it minimal): Resist the urge to highlight everything that seems interesting. Instead, focus on the key ideas that resonate with your purpose for reading.
  • Write margin notes or questions: Use the margins to jot down quick reflections, questions, or connections to other ideas. If you’re reading digitally, take advantage of built-in annotation tools. These notes will help you engage with the text on a deeper level.
  • Pause after each chapter to summarize:
    • Write a brief summary of the chapter’s main takeaways in your own words.
    • Note 1-2 examples or case studies that stood out to you.
    • Reflect on a question or insight you want to revisit later—this could spark further learning.
  • Look for action points: Nonfiction books often contain practical advice or strategies. Identify what you can apply immediately in your work, personal life, or habits. Even a small step can turn an idea into a lasting change.

Reading actively may take a little extra time, but it ensures the ideas stay with you long after you’ve turned the final page.

After you finish reading

What you do after finishing a nonfiction book is just as important as how you read it. The goal is to solidify what you’ve learned and make it easily accessible for the future. Here’s how:

  • Create a 5-minute summary:
    • Write down the book’s core ideas in your own words. This forces your brain to actively process the material rather than simply recalling phrases from the text.
    • Include a few memorable quotes or examples that struck a chord with you.
  • Add notes to your "Knowledge System": Whether you use a journal, a digital app like Notion or Obsidian, or even sticky notes, capture your thoughts in a place where you can easily revisit them. Organize your notes by themes, topics, or actionable takeaways.
  • Use the Feynman Technique: One of the best ways to solidify your understanding is to teach it to someone else. Try explaining the book’s ideas to a friend, writing a blog post, or even recording a short video for yourself. The act of teaching shows gaps in your understanding and helps reinforce what you know.
  • Review highlights using spaced repetition: Memory fades unless you revisit the material. Review your notes and highlights a week after finishing the book, then again monthly. Spaced repetition strengthens your recall over time and ensures that the insights remain fresh when you need them.

By taking these steps, you’ll transform your reading into long-term learning and make the book’s lessons a lasting part of your life.

Revealed in those intricate designs struck in gold, silver, and bronze was the epic story of the Roman Empire.

Our human nervous system has the power to cope with high stress, but not when it’s been ground down by the relentless stimuli of today’s world. Over time, these persistent demands leave us burnt out because our nervous system is stuck in survival mode, making it hard to make decisions, rest, solve problems, be mindful, and set boundaries. We slip into autopilot, making us prone to mistakes, and toxic behaviors that impact professional and personal relationships.

It is not the man who has too little, but the man who craves more, that is poor. – Seneca Hi Reader, reading is often seen as a quiet, solitary activity—just you, a book, and maybe a cup of coffee. And while that sounds amazing, what if I told you that reading in public could be even more powerful? I don’t mean reading on public transport (though that’s great too). I’m talking about reading as part of a network—discussing books, sharing ideas, and learning alongside others. Some of my biggest...

There are darknesses in life and there are lights; you are one of the lights, the light of all lights. – Bram Stoker, Dracula Hi Reader, have you ever read a book, loved it, and then… never thought about it again?
