In fact I've graduated from being a keeper of endless scraps of paper to something called a bullet journal. Have you heard of them? It's a craze that's been sweeping the world for the past few years.
If you want to know what I mean search pinterest or google images for "bullet journal" – there are hundreds of examples, ranging from the flamboyant and artistic, to the terse and spare -- and even the ever-so-slightly anal.
A bullet journal is a way of organizing your life, keeping lists of what you need to do (or eat or exercise or whatever.) Some people take it to extremes and create elaborate and detailed lists for almost every aspect of their lives. There is endless scope for perfectionism and procrastination with the bullet journal. It also works — or it does for me.
