When you learn something more in depth, you are less likely to forget it. When you learn other things adjacent to the topic at hand, but related in some way, you’re less likely to forget things as you build more and more of a frame of reference around it.

First you need to test your recall after a short period, then after a longer period, etc. Memorization skills isn’t something you’re inherently good or bad at, or are born with: it’s a skill you can absolutely learn!
