I have been looking for a good to-do ecosystem for so long that I ended up with pen and paper. Hear me out. I bought very nice a6 paper notebook and very comfortable ball pen an I just enjoy having this one non-digital, offline thing. After years of not writing with pen and doing most of my life management digitally, having this one thing this way… It’s hard to explain but I enjoy. I even try to write with nice joined-up writing. At the beginning of the notebook I have next todos section, in the middle I have in progress long term todos and at the back I have inbox.
