Actively building a memory palace while I read or listen to things was a game changer for me. It's very draining though so I can only do it for about 30 minutes at a time but generally that's enough. I'm sure spaced repetition works well for most but it felt like work and I didn't want to take joy out of learning. Memory palace was a way to do that.
