Do You Review Your Mistakes?

It's not just about the quantity of training but it's also about the quality of training. So, do you focus on a mistake because I know when we're memorizing we can have a lot of mistakes and a lot of reasons why we didn't recall something. There's so many different things. Do you focus on one aspect at a time, or do you spread it out and and try to work on them simultaneously. What does, what does that look like? I just wonder two things like why I made a mistake. And what is the thing that I should do to avoid it. It really really helped me to make this feedback to have a notebook that I write down everything.
