How I Remember What I've Learned

I remember things by writing them down and reading them later. I take notes during breaks or just after Naginata practice. Later I type them up into a reference document and I read my books to make sure I didn't make any mistakes in my notes or forget to add any details. I read my reference document once in a while and bring it to practice with me.

And of course, repetition in practice helps a lot too.
