I keep a pocket notebook with me at all times, for writing down anything and everything. My notebooks contain things I need to do around the house, article outlines, business ideas, meeting notes, and more. I like thin, pocket-sized notebooks because they are easier to carry and because it only takes 2–3 weeks to fill them up, which is a nice interval for processing their contents.
I’m explaining how I use my notebooks because the way I use them has a lot to do with which notebooks I prefer. So does the pen I carry everywhere with me — a Fischer Space Pen.
So, my notebooks need to last 2–3 weeks and they need to be able to survive being stored in my back pocket most of that time. And the paper needs to hold up to a Fischer Space Pen (which is roughly equivalent to most ballpoint pens). With those requirements in mind, here are the ones I have tried, and my thoughts on each.
