Re-reading feels like studying. It mostly isn't.

Highlight the page. Read it again. It starts to feel familiar, and familiar feels like knowing.

Then someone asks you about it and there's nothing there.

Recognising something and being able to bring it back are different skills. Re-reading trains the first. Real life usually asks for the second.

This week's trip

Take something you want to keep, like a chapter, an article or the notes from a meeting. Then:

1. Read it once, properly.
2. Close it. Write down or say everything you can remember. Be honest. It'll feel worse than re-reading did, and that's the point.
3. Open it and check what you missed. Those gaps are now the only part you need to study.
4. Do it again tomorrow, then in a few days, then in a week or so. Let it get a little hard each time before you try again.

Researchers call the second step retrieval practice, and the fourth spacing. Neither one needs an app or special talent, only the willingness to feel a bit stuck for a minute.

The rule of thumb

If your studying feels smooth, you're probably not learning much. If you have to stop and reach for it, you're doing the part that counts.

Pick one thing you read this week. Tomorrow morning, before you look at it again, see how much you can get back.
