Teach it to learn it

You read an article, nod along, and a week later you can't explain it. Understanding often feels complete until you try to put it into your own words.

The idea

After you learn something, explain it to someone else in plain language — a friend, a colleague, or an imaginary twelve-year-old. Where you get stuck is exactly where your understanding has a gap.

How to do it in 10 minutes

1. Pick one idea you learned this week.

2. Explain it out loud or on paper in five sentences, without jargon.

3. Mark the sentence where you hesitated. That's your gap.

4. Go back to the source for that one point only.

5. Explain it again. It's usually shorter the second time.

Why it works

• You have to organise the idea, not just recognise it.
• Gaps become visible instead of hidden behind familiar words.
• The other person's questions show you what you skipped.

Make it social

Swap topics with a friend: each of you explains one thing you learned this week, then asks the other one question. Fifteen minutes, and you both leave knowing two things better.
