How to Recall an Entire Book in 5 Minutes or Less

How to Recall an Entire Book in 5 Minutes or Less

Have you ever read a great book, and after only a short period of time could recall just one or two ideas from it? It is very frustrating - and it happens all the time. But there’s a way to avoid forgetting what you have read and, if you do, instantly refresh it in your mind.

Reading Goals, Cheated

The key to reading effectively is to be fully engaged in what you are reading. Underlining, questioning, taking notes – these all help – but there’s one single element that is essential if you want to read effectively: you need to know what your goal is. This is standard advice, and is indeed a good one. But if you want your reading to be truly effective and long-lasting, you need more than simply a goal: you need a very specific and tangible one.

Take, for example, a book such as Getting Things Done. The goal “to get more organized” would be good enough - but just as a generic goal, not as a specific one. A generic goal may be enough to motivate you to start reading a book, but won’t be truly effective by itself to keep you fully involved while reading it. We need something more concrete.

The problem is that we only know the specifics of a book after actually reading it. So what should we do as we want to set a specific goal beforehand? We cheat.

I’ve found that one of the most effective goals to set when reading a book is to commit yourself to create a mind map of it.

This will serve as a specific goal that you can use for any book. Yes, having a “general-purpose specific goal” certainly feels like cheating, but you won’t believe how effective it is. It will really help boosting your reading comprehension; and the best part is that you’ll have a book summary you can revisit at anytime. Contrary to regular book summaries, due to the specific properties of mind maps, you’ll be able to review it at lightning speed, quite often at a single glance.

Top 3 Benefits of Mind Mapping a Book

1. Boost Comprehension While Reading

Being sharply focused on creating such a specific deliverable as a mind map will get you 100% engaged in your reading, guaranteed.

Moreover, every time you reach for your mind map to add more information, you’ll be looking and recalling what’s already in there. In fact, this constant reinforcement works so well, it usually takes months before you need referring to the mind map again.

2. Quickly Review the Entire Book Anytime

This is when mind mapping really shines when compared to other note-taking techniques. It is absolutely amazing what happens when you look at a mind map months or even years after you created it. It is like rereading the entire book in just a glance.

When you first read the book using this method, you did it in such an active manner that by just quickly scanning the mind map brings you all the memories from the book – even the ones you didn’t include in your mind map. In fact, the neural connections formed are so strong that even the emotions you felt at the time often resurface. And with such a personalized and handy summary, you really don’t need more than 5 minutes to review it.

3. Distill the Real Substance of the Book

It is not rare for long books resulting in small mind maps. By creating a mind map, the real content of the book becomes evident. Not everything in a book is straight to the point: authors (validly) use repetition, stories and examples to build and elaborate important points. All you need to do is use standard mind mapping features to reflect that importance: use bold, write your topics in bigger letters or different colors. With your personalized mind map, you’ll be able to trim all fat while keeping the relationships and the relative importance of each topic intact.

Tips to Get Started

Keep the Flow

Avoid reading and creating the mind map simultaneously, as that will disrupt your reading flow. Circle, underline and take notes while reading, pre-selecting the important concepts and passages for your summary. This intermediary step not only keeps you in context and engaged in the book, but also makes it much easier to quickly create your mind map once you read the relevant parts of the book. And by doing this, you’ll have yet another content reinforcement in the process.

Sleep on It

Try not to work on your mind map right after reading the book – let your mind chew on what you have read for a while first. Doing it the next day is a good rule of thumb. If you read every day, a good way of doing it is by working on your mind map for yesterday’s topic right before today’s reading session. Also, try not to get your reading too far ahead of your mind mapping – you’ll lose the benefits of repetitive reinforcement and feel overwhelmed if there’s too much content to add in a single sit.

Use Dual Bookmarking

Instead of using just one bookmark, use an extra one to indicate up to where your book has been mapped. I also recommend using colored Post-it flags, so you won’t need to worry about your second bookmark falling while you’re reading.

Try It

Won’t reading books with this method take much longer than usual? Sure it will – but what’s the point in leafing through several books, only retaining a tiny amount of their content - and only for a short period of time?

If you’re just reading casually and you feel this method is overkill, you are probably right – don’t force yourself to use it, by all means. But if you get your hands on a great book – and there are so many out there – please give mind mapping a try. You won’t regret taking these extra steps to make your books really last in your mind.

    Nice method; I’ll definitely try it, though I’m a litle bit skeptic to mind mapping technique.

  2. 2 Giuliano

    The applicabilities of this tool are incredible. I´ve never used mind mapping for an entire book, but for specifc chapters of my technical ones. I gotta expand it for the other kind of readings, and try to register the whole reading into a mind map. But for this, discipline is essential. How about bringing us some material about this subject? I know you have a lot of tips referring to this topic.

    olejorik:
    When you try it, please report back your experiences. I’d love to know how it worked for you.

    Giuliano:
    You’re right when you say it takes a little discipline. Thanks for your suggestion. I will definitely cover this topic here in the future.

    This seems like a powerful technique if you have the motivation to use it.

    The way I feed myself on information has changed these days, meaning that reading isn’t taking as much time as it did at some point.
    Science has shown that in the order of their “stickiness”, the best learning methods are: 1. Visual; 2. Auditory; 3. Reading. And so if reading is on the third place and takes the most time, using the Pareto (80/20) principle, I focus more on the auditory and visual methods. I prefer listening to an audio book because I can set the playing speed to 1.8x and save a lot of time, while absorbing very much information.

    But I’ll definitely try out the tips that you wrote about here. I’m sure they’ll create even more time!

  5. 5 Luciano Passuello

    Very good points, Armand.

    Visual is definitely the way to go.
    I consider this technique of mind mapping books as a time investment: since you already invested time in reading, why not invest a little more in transforming the book in a visual mind map, right? This way you won’t ever need to read the book again, saving you much more time - and getting all the benefits of visual learning.

    This seems like an interesting method, that could really help me out. I often have to read books for courses and after Im finished I realize that I dont remember a thing I read.

    Few questions, for getting started, do you just use this for non-fiction, or fiction books too? What type of things do you write in fiction books, as I’m having trouble visualizing it. Maybe you could post an example of one you’ve done?

    I am reluctant to follow the reading advice of a site that begins with the following sentence: The key to reading effectively is to be fully engaged in what are reading.

  8. 8 Luciano Passuello

    GS:
    I have used this technique only for non-fiction books so far. However, I’m sure you can use it for fiction, too. You can create, for example, a branch with the main characters and their traits; one branch for the main happenings in the plot, another for the places, and so on.
    I plan to publish some mind maps I’ve made for some non-fiction books soon. Not fiction, I know, but maybe that can help giving you some ideas.

    josephlowery:
    Ah – you got me! Thanks for pointing that out – I’ve fixed it in the post.

    I’m a great fan of mind-mapping and am always interested to hear of new techniques or uses of mind-mapping. I have mind mapped a book before and can vouch for its usefulness.

  10. 10 Brad Sayers

    loved the post. i read tons of non fiction and am a serious note taker. i brutalize a book with marks (trying hard to keep it minimal of course). I read through it and then at a later date go through page by page and begin selecting points to put into my notes. notes are in word and much hyperlinked to other documents.
    i am always thinking of ways to better the process and will try mind mapping. question: is there much of a rough / draft process in mapping before one gets to a ‘final’ map? Cheerio, Brad

  11. 11 Luciano Passuello

    Hi Brad, thanks for your comment. After you try mind mapping, please let me know how it compares to your current note taking method.

    I don’t follow a formal draft process when mind mapping. That said, the first mind map is usually not the final one. During the development of large maps such as the ones from books, it is very common to find new relationships that you didn’t notice when reading — that’s why I recommend doing it using software, so you can easily rearrange and add topics.
