When I'm learning something there is a pretty simple trick I use which works for me. 1, I have the belief that I can understand the material. This is the most important part because if you do not believe you can understand the material then you will always fail to understand the material. If you do not have this, figure out why and address that first. 2, I will suck on a mint, since I was told as a child that sucking on a mint dilates the blood vessels in your head and gets more oxygen to your brain, more brain blood, more brain power, right? Honestly, though, it's more helpful for cram sessions and tests for some reason. If you're casually learning you can skip this. 3, Revisit the material a day or two later, especially if you had difficulty with it. This showed its hand in college maths a lot. I would fight for half an hour on a difficult problem at first, then come back two days later and try a similar problem and kill it in 5 minutes. Something about it being harder to carve a new line into a rock than to retrace it after the fact. Doing this solidifies confidence in the new thing that you have learned. 4, After I have read and revisited the material, I will tell what I have learned to an imaginary child me as though I am teaching them what I have learned. If you can't teach it, you don't understand it. Seems to work pretty well.
