In reply to ias_87.

Most of these cards get material of a planning/calendaring nature and my daily to do list material. (Here's a somewhat sanitized and broadly "prettier" version than happens regularly as an example: https://boffosocko.com/wp-content/uploads/2023/07/wp-1690441223893-scaled.jpg) Generally besides being pulled out a few at a time for daily/weekly use, they all stay in the same place in date order. In practice, I also put some diary/journal material either on them or on separate cards that get filed and indexed with them.

I have separate Eisenhower section of cards that has project material that is sorted by priority. (Photo: https://boffosocko.com/wp-content/uploads/2025/11/wp-17637674618087127597355356991352.jpg) These tend to have more motion around the system.

There's also a section filed by project, particularly for bigger/longer term projects that have multiple moving parts delineated with sub-to-do lists.

Here's a few posts where I've delineated parts along with pictures of some cards:

Often I'll also write quick reminders on the daily cards that gets transferred to their own separate card and get fleshed out and filed elsewhere (commonplace and zettelkasten-like practice; see: https://boffosocko.com/research/zettelkasten-commonplace-books-and-note-taking-collection/)

If you practice any of the Memindex, diary, GTD, Bullet Journal, 43 folders, or tickler file traditions, it's exactly those, just done on index cards rather than on paper in a notebook. There's a lot of similar ideas around the title "hipster PDA".
