I used a paper planner for a long time and can tell you what worked for me.
On my person at all times: UCT
In my satchel, which was always at hand: planner, Inbox folder, Action support folder
My planner was set up according to DA's 3-ring binder recommendations: 8 tabs.
The planner contained:
2) Projects List
3) Agendas by meeting or person
4) Next Actions lists by Context
5) Project Support (if a project required a formal Project Plan, I carried it here)
6) Reference Material (I carried a coded list of account numbers, birthdays, etc. This section received attention during each Weekly Review to keep it slim.)
7) Address book
Inbox - blank paper
In my desk, I kept my Tickler folder, Project Support files, and Reference files.
To save space, I kept running text files for such things as Address book.
New information would be written in by hand, and then the text file was updated during the Weekly Review, with a new printout for the following week. Otherwise, the pages would start to look ugly.
