How to actually remember the best lines from the books you read

Imagine you’re reading a book you find genuinely interesting. But not just that. You feel like you’re learning something every couple of pages, like the book keeps dropping little nuggets of wisdom that you need to pick up and save somewhere.

Imagine you’re reading a book that makes you feel something profound, the kind where, in that instant, you start to wonder if you’ll be the same person once you finish it. You find a line, or a couple of lines on a page, that blow your mind completely or change your heartbeat in a second, and you want to record those words somewhere, anywhere.

Books have always had this power. And we can take it one step further: to carry those emotions with us, to remember those precious moments on another day, or to feel inspired right when we’re about to do something that matters to us.

After a few books, you lose track

I’m a big fan of highlighting books. It doesn’t matter if it’s a textbook, a novel, or even a light novel. I’ve always wanted to keep a record of the words that made a real impression on me, so I underline the best sentences on a page and leave a little mark next to them. It sounds great in theory. In practice, after a few books, it’s surprisingly easy to lose track of everything you went to the trouble of marking.

I’ve tried saving quotes two ways. The first was notebooks, by hand. Handwriting a line does help you remember it, at least at first. But once you’ve filled pages with hundreds of quotes across several notebooks, recalling any specific one becomes impossible. The second was the Notes app. It’s more convenient, and you carry your whole collection in your pocket. But it runs into the exact same wall at volume, simply because Notes was never designed for this.

The missing piece is recall, not storage

Here’s what all of those methods have in common, and what’s missing from almost every one of them: they’re built for storing, not for recalling.

Highlighting stores the line in the book. The notebook stores it on paper. Notes stores it on your phone. All three are good at keeping the words. None of them ever hand the words back to you. And if you actually want to relive the moment you first found a quote, you need something that does the opposite of storing: something that brings the line back and grabs your attention again, even for just a few seconds, on an ordinary day.

This is the broader problem I wrote about in what to do with all the quotes you screenshot and forget. With books it’s even more acute, because the lines that move you most are often buried the deepest, in a book you finished months ago and haven’t opened since.

Let me give you one of mine. I’m a big fan of the work done by 37signals. DHH and Jason Fried are personal heroes of mine, because of their vision for business, how they see collaboration, the way they pioneered remote work, and most importantly, their philosophy around productivity. One of my favorite books of theirs is Rework, and even in 2026, it never gets old. In one of the chapters of its Productivity section, there’s a quote that literally rocked my world the first time I read it: “The way you build momentum is by getting something done and then moving on to the next thing. No one likes to be stuck on an endless project with no finish line in sight.” I was just starting my professional career, and my first job was at a Fortune 500 company, so it was as big as it gets. I still remember the days when I read that quote and the rest of the book, and discovered that there were so many other ways the business world could work. At the time, I was dealing with the boredom, the monotony, and the slow pace that working for a company that big usually means. Of course I will always treasure that first job and the people I met there, but this quote made me realize that you could work in a completely different way, and that the feeling of achievement could take many forms. We just need to discover the one thing that really keeps us going. I got lucky with that one. It stuck with me on its own. But most of the lines that move me don’t stick like that, and I would rather not leave the best ones to chance.

That recall problem is the whole reason the app I built, Kandou, works the way it does. You save a quote once, and Kandou brings it back to you on a rotation you choose, on its main screen and on a Home Screen widget. The line you loved in a book last spring resurfaces while you’re just checking the time. I told the longer story of why I built it here.

Revisiting your quotes makes you a better reader

Here’s the part I didn’t expect. When you start reliving your quotes regularly, something compounds.

Seeing the lines you’ve saved come back, again and again, slowly makes you more receptive to the wisdom in whatever you read next. Patterns start to form. You begin to notice the kind of sentence that tends to matter to you, and you spot it faster on the page. The collecting sharpens the reading, and the reading feeds the collecting. It turns into a loop, and the inspiration keeps flowing through it.

That loop is the real payoff. Not a tidy archive of quotes you’ll never open, but a habit that quietly makes you a more attentive reader over time.

You don’t need an expensive system

None of this requires spending a lot of money on some elaborate setup, and that’s true whether you go analog or digital. A plain notebook works, if you build the habit of rereading it. A free app works too. The point was never the price of the tool. It’s whether the system you choose actually helps the words resurface, instead of just swallowing them.

If you read the way I do, marking lines you don’t want to lose, Kandou is on the App Store, free for your first 15 quotes. It won’t make you highlight any less. It will just make sure the lines you highlight find their way back to you.
