inspiration I frequently lost pencils and never took notes for most of my academic career. Eventually I got to the point in my self-studying and in my learning were notes was necessary. I find that writing things down can 2-3x the amount of stuff I can hold in my head at once, while making it easier to reference, and makes me remember it for longer and quicker. pencils I prefer pencils to pens as I can erase pencil but not pen.
