How to Keep Track of Your Knowledge

I mentioned not making mastery earlier I wanted to ask you a question related to personal knowledge management. What are some things you do to kind of just keep track of all this knowledge, you know, I wish I were better at it for sure. So that's something that I make a practice of as well I usually got two or three going at once. Having a good outline for everything helps me because then I insert all a lot of my thinking and then it's like oh right right that goes there that goes there.
