For a long time I was doing a bullet journal for management and another notebook for notes, written in shorthand. was great for when i worked in an office, didn't have to lug around my computer. The downside was that deep searching for things was impossible. You tell me the day and I could find it but 3 months about at some point we talked about X...
Now that I've been work from home for 6 years I've switched to todo.txt and Obsidian (vimwiki set to output the same location). Syncthing to keep computer and phone working.
i also do 43 Folders for intake of mail and tasks with some sort of physical medium.
As for workflow I have a daily note template that has:
- Morning routine checklist (already filled out)
- Curated To Do list for the day
- Section for Meetings / Calls / One Off Immediate Task
- General Notes
- "For tomorrow..."
My routine has steps for filling out the rest of the notes and lists, checking emails, 43 folders, etc. This way all i really have to do is follow the steps.
