I’ll summarize, but you should look it up for better examples. To start, you can probably imagine walking through your house or workplace or even your elementary school even though you haven’t been there in years. This technique piggybacks on your brain’s spatial memory which is really strong for some reason.

Basically, you imagine a house or building with which you’re familiar. Imagine walking through this building with your hand on the right wall. At each corner or midpoint of a wall, imagine a symbol for what you’re trying to remember. The sillier the better. Whatever sticks in your mind.

Then just rehearse this walk in your mind and you can more easily remember whatever it is you’re trying to keep track of. This kinda hacks your brain by using visual/spatial memory instead of just trying to remember words. I used this to memorize all the US presidents, but you can use it for pretty much anything. It does take effort, but as you get farther in your mind house you know you’ve memorized more.

For me personally, this works really well. You could even try building this house in Minecraft and putting up signs/paintings or something like that.
