I need to write down things g in order to remember them, that's why I wanted to have both a book to read (according to my level which is bad, but that's not the point) and a notebook to take notes of important points. I'm still 100% homeworking due to COVID, but it will be soon over and I'd rather travel lightly in the commutes. So being able to work only with my sage during my lunch pause seemed attractive. I don't pretend being better than anybody. In the process of learning, you have to choose an efficient way for yourself of studying. Kanjis need a lot of repetitions to stay in your mind. With my sage notebook, I could go back over the ones I have already seen. With Kanji on uneven pages and the meaning next page, I can test myself and see which ones I remember and which ones I need to work on
