Earlier this year I bought the Plannerism Planner because I liked the idea of having a planner that helped me set goals. I used it for a few months and enjoyed it, but found the paper not working quite well with my fountain pens and ink. So I strayed.
I bought a Leuchtturm1917 Academic Week Planner because I got hooked on the columns. And Leuchtturms have paper that works well with fountain pens and inks.
