The approach the author used here is similar to using flashcard apps like anki, except not as well fleshed out. Normally, in a flashcard app, you would write down a question and an answer. So you can review the question, and see if you can answer it or not. He wrote this down all as a oneliner for each of his "learnings". Its nice to see a frequency graph to see how often you are learning, but it doesn't really serve a purpose besides showing how inconsistent you are learning new things. I would highly suggest anyone interested in the authors approach to learning to read these 2 articles about spaced-repetition-learning and flashcards, which goes into much more detail. https://www.jackkinsella.ie/articles/janki-method https://www.jackkinsella.ie/articles/janki-method. https://www.supermemo.com/en/articles/20rules https://www.supermemo.com/en/articles/20rules Not all things benefit equally from writing things down learned / flashcards. Some things can only be learned through practice, such as learning a sport you aren't familiar with such as football. But flashcards can be beneficial here to learn about the rules of football, the mechanics, terminology, etc. The hardest part is differentiating what pieces of information benefit from using flashcards and which don't, and consistently recognizing when new information is learned / making a flashcard for it
