This may seem very small and really unimportant – but making usable notes is an amazing skill to aquire! If you keep notes badly, you will end up with piles of incoherent pieces of important information. So instead of tangibly remembering things you need to remember, or recording things you need to do, or writing down important or special things you want to recall — you end up with another problem. Therefore make good notes — ones that help and serve you.
