How to learn

How to remember what you read

Reading a chapter and remembering almost nothing of it a week later is normal, and the problem is not your memory but the way you read. Remembering starts before the first page and ends after the last one. Here is what to do at each stage.

Before reading: five minutes of preview#

Flip through the whole chapter: headings, highlighted text, figures, the questions at the end. Ask yourself what the chapter seems to be about and what you already know about it. The preview builds a frame for the details to land on later. Without it, your brain gets a stream of separate facts and does not know where to put them.

Read the questions at the end of the chapter before you start — now you are reading with the aim of finding the answers.

While reading: small portions#

Read a section, close the book and retell it in one or two sentences. If you cannot, reread — not the whole chapter, only that section. Highlighting is almost useless: it feels like work but does not make you think. Short notes in the margin or in a file are better — a question, an example, a link to something you already know.

Take breaks. Twenty to thirty minutes of attentive reading and a short pause give more than two hours without stopping.

After reading: retelling and notes#

Right after the chapter, write down its main ideas from memory — three to five points. Then open the book and compare: what you missed, what you distorted. This comparison matters more than the retelling itself: mistakes are remembered well when you found them yourself. The principle is covered in active recall.

Note down not quotations but your own wording and examples. If the book has problems, solve at least some of them: for a textbook that is the main test of understanding.

After a day, a week, a month#

Without review even a well-studied chapter gradually fades. Come back to your notes after a day, a week and a month. Each time, first try to recall the main ideas, and only then look at the notes. Material you returned to three times stays for a long time — the schedule is described in spaced repetition.

Connect it with what you already know#

New material is remembered better when it is hooked onto old. Ask yourself: what is this like? Where have I seen it? How does it differ from what I knew before? Such connections are the best reason to write down an example from your own life or work.

For fiction#

The goal here is different — not to learn but to keep your impressions and thoughts. A short note after every few chapters is enough: what happened, what stuck, what question came up. After the book, a paragraph on what it changed in how you see things. A year later such notes read like a diary.

How much to read at once#

For a textbook a good portion is one section or ten to fifteen pages per session. More usually means the retelling becomes shallow. More on working through a whole book is in how to study from a textbook.

Step-by-step plan

  1. Preview the chapterHeadings, highlights, questions at the end — five minutes.
  2. Read in portionsA section — close the book — retell it in one or two sentences.
  3. Retell after the chapterThree to five ideas from memory, then compare with the book.
  4. Problems and examplesSolve some of the exercises, write down your own example.
  5. ReviewAfter a day, a week, a month — recall first, then check.

How to learn How to learn vocabulary The main problem with memorising words is not that they are hard to remember but that people learn the wrong words in the wrong form. A list of a hundred random nouns fades within a week, while twenty frequent verbs in real phrases stay. Here is what to change. How to learn Active recall Active recall means reviewing through a question rather than through reading. You close the book and try to pull the answer out of memory. It is harder than rereading, and that is exactly why it works: memory gets stronger at the moment of effort. How to learn Spaced repetition Spaced repetition means coming back to material not whenever you feel like it but at the moment it starts to fade. You spend less time memorising and it stays with you longer. The method is simple, and you can use it without any special software. How to learn Procrastination Procrastination is when you put something off of your own accord, with nothing stopping you, knowing that delaying will only make things worse. That is the strange part: the choice is deliberate and against your own interest. Let us look at where it comes from and why "just get started" barely helps. How to learn How to study from a textbook on your own A textbook is one of the most reliable sources for self-study: it has structure, exercises and answers.

Company knowledge base A company knowledge base rarely dies for lack of tools. It dies because nobody owns the pages and they quietly go out of date. Here is how to set up a base that has owners, a history and a clear way to change it. Personal knowledge base A personal knowledge base is not an archive of everything you have read. It is a set of your own notes, linked to each other, that you keep coming back to. Here is how to set one up so it works instead of turning into a dump of links.
