It feels counterintuitive and time wasting to copy notes from a written book, to your own words in a notebook, then transcribing it in a literature note, and finally into a permanent note...
But repetition helps with memory. Then, you will remember the notes better, and you will also be able to remove some notes that do not seems so relevant anymore. Yes, it's a lot of work, but the ideas that come out of it will be of greater quality. And as you know, Quality over quantity!
