Whats a small habit or routine that significantly boosted your learning retention?

We all talk about big learning strategies. Read more books. Take courses. But sometimes it's the tiny stuff that makes the biggest difference.

Maybe it's reviewing notes right before bed. Or explaining a new concept to your pet. Could be listening to a specific type of music while studying.

What's that one little thing you do consistently that you feel genuinely helps you remember what you've learned?
