I see, that’s nice. I asked for a7 format since I want a portable « device ». I currently am following the today system method with my stuff from https://www.x17.de/de/mind-papers/karteikarten-lernkarten-karteikartenbox-karteikartenkasten-lernkartei-mindpapers/.

The creator of the Today System was definitely aware of GTD, Bullet Journal and likely other methods, and intended his to be an added piece on top of them.

Melange of GTD, card index, and gamification....

Update 2024-01-04: I knew I had heard/seen this system before, but not delved into it deeply. I hadn't seen anyone either using it or refer to it by name in the wild until yesterday. All the prior mentions were people sharing the URLs as a thing rather than as something they used.

Alas, no definitions for the "vocabulary" of the Today System...

Mike Sturm ostensible created the Today System for his own use.

Is the system productized? Is he charging something for it or just proselytizing it?

The Discord Group for Today System seems to be dead quiet. No significant posting there since January 2023 and most activity seems to be in 2021-2022 time frame, so likely a new player on the market at that point?

The Today System:

A simple, yet scalable personal productivity system, centered around a single 3 x 5″ index card.

used by u/runslack

The Analog system has a thin metal divider that separates two sections in the base. The broad suggestion is to use this space as storage and the divider for separating the blank stock of cards from used cards. One could also separate the next/someday cards from the today cards (new and finished).

The divider serves as a tabbed divider in many systems, but here there are only a total of three slots for differentiation: one slot for one card with today's list, and two other spaces for other cards that the user can determine their uses for. This definitely makes the system incredibly simple and minimal.

It's only slightly different from the old common Park Sherman Co. desk note pad systems which sometimes had a universal calendar and one tray space for notes.

Though the Analog system clearly delineates cards of to do lists as "Today", "Next", "Someday", I've definitely seen this sort of delineation well before this system.

What other systems explicitly use this framing or similar framings?

While the today / next / someday cards are labeled, they're also color coded (white, light tan, tan) to help distinguish them.

Though not defined in the Analog system, these differently colored cards could also be used to indicate different sorts of data, though one would need to potentially ignore the pre-printed labels of "Today", "Next", "Someday".

The Analog system utilizes a simplified version of an Eisenhower matrix which we'll call "today / next / someday" as a means of prioritizing to do list items on a temporal basis.

The someday card is described as being not only for individual to do items, but "big picture" goals.
