Rewrite ideas in your own words

Never copy-paste; translate the idea into your own language.

Why it works

Restating an idea in your own words forces elaboration — you have to actually understand it well enough to reconstruct it, which builds richer, more connected memory than copying does. The act of generating the phrasing yourself also exposes where your understanding is thin. Copying preserves words; rewriting builds comprehension.

How to do it

1. After reading something worth keeping, look away and write it in your own words.
2. Capture what the idea means and why it matters, not just what it said.
3. If you cannot restate it without the source, you have not understood it yet — reread, then retry.

Evidence

Rewriting in your own words draws on the elaboration and generation effects, both well supported: generating and elaborating material yields stronger, more durable learning than passively reproducing it. (rct)

The generation and elaboration effects are robust in controlled studies, but the specific Zettelkasten workflow built on them has not itself been trialed.

Common mistake

Saving highlights and quotes verbatim and feeling productive, while skipping the rewriting that is the entire point — accumulating other people’s words you never internalized.
