Bullet Journaling is popular right now. I was looking at them and thought you could use shorthand for your items. You could even use them to write in shorthand and keep them private. However, you can use shorthand for all pages or any pages you want.
If you have a journal and you feel comfortable sharing a page, please feel free to do so on here.
Here's a KEY for journals. I just combined a few to give you a list of suggestions. When you write "task" you can add the extensions after. I put the "c" for "cancelled" through the word "task" to show that it was cancelled or not needed to do.
Here's one idea. I would love others. Because my phone calendar I set to start on Monday, I did the same here. I wrote some numerals in shorthand, I did a sample of what I thought might work under the Numerals in Shorthand thread. Green highlighted means payday (green is the color of money). Pink highlighted means holiday and off work (pink is a fun color). I underlined the days that were mentioned on the left for quick and easy reference.
"Gregg Shorthand had achieved the most extraordinary success ever attained by any system in the history of shorthand." John Robert Gregg, 1922
I see bullet journal pages for shopping lists. I use a phone app, but maybe as a general shopping list of things you repeatedly buy or see what special items you buy once in a while.
Or these lists work when planning menu's and you could use your bullet journal for that. One column of the steno pad for your meal planning and one for your shopping list organized (such as by aisle in store or by menu items) then transfer to a main shopping list or app.
Need ideas for shorthand? What's On Your Shopping List drill gives you some drills to practice if you want before putting them in your bullet journal.
Here's a sample page for a Daily Menu. Three lines for each day for breakfast, lunch and dinner. It would be a great way to practice the days of the week. On the bottom I added "special menu:" On the left I wrote "shopping list:" even though it's not great. You could change the second column to what you need for the menu, then check your pantry cupboards and see what you have. Use that to update your main shopping list.
Because you may prefer not to use a steno book (although it could work--see Notebooksfor different ideas on using them in general) for your main bullet journal, you could use different types. Here are a few things that I've found and read.
Soft covers vs Hard Covers This is a personal preference. Remember that you can change at any time to try out something different to see what you might prefer. Also consider if you will be practicing writing shorthand notes or dictation in them on your lap or on the go.
Small, medium, large Notebooks This is a preference as well. If you plan to carry one with you, you may want the small one and maybe even a softcover. There are some that are very thin soft cover (Moleskine carries a line like that, I believe called Cashier). These could fit in a shirt front pocket. If you want a regular size one, a medium seems to be the preferred size. The large if you have a very busy life and need to track a lot of things (or just want room to practice more shorthand). Remember that this notebook may not cover one year, so use what size you prefer.
Paper Quality Depending on the type of pen you use (read up on different pens for shorthand here), you may need to use a thicker page if you plan to write on both sides. Note that the majority of notebooks will have "ghosting" (where you can see a bit of the writing from the previous page) but you don't want some where the ink bleeds through.
Paper Design There are a lot of ideas on the design you want. Lined, blank, grid, etc. Most love the dot version. This might work best for shorthand so you can have almost a blank page to write your shorthand, but still a little guide of dots to help you write straight across. I haven't tried one, so I'm not sure. I didn't know they had these, so I was using blank notebooks for my everyday life although not quiet a bullet journal, as the early shorthand textbooks were blank, so it worked for me. You might be able to find one with wider ruled lines that would work, or you can skip lines (I've skipped lines before--even on steno notebooks).
