I have totally been where you are. I work in a deadline driven industry where I need to proactively manage multiple clients, projects and deadlines, not tto bemention being married to a busy woman and having a 9 month old.
About 6 months ago I embraced the paper planner again. Mine is a week at a glance and contains meetings, appointments, deadlines and most important, promises made. I also carry a small notepad in my back pocket and use it when I need to write something down before I forget it, but don’t have direct access to my planner.
I tried using Microsoft Outlook calendar, Google calendar, and probably a dozen different apps. for me, with the blend of eating to manage home and work in a single place, as well as being extremely visual, the paper-based planner is the only one that’s ever worked.
