Midori MD Notebook - A6 Grid Paper, Pilot FriXion Ball Slim Biz Gel Pen - 0.38 mm, and sticky notes helped me organize my life the last two years.
I never knew an eraseable pen could be so good. Midori paper is on another level.
I love jetpens. I'm trying out the Hobonichi Techo Weeks as a 2022 journal for more structure. But I'll always have a Midori MD for free flowing thoughts or sketches.
They even have an interesting video on how they organize and pack orders. https://youtu.be/1Bi2Xys-ces
