Right now I've got several active books, and I'm going to try to keep up with them this year.
From the top of the pile to the bottom (or from right to left, if you'd rather):
E. E. Cummings: I received this little book in a subscription box. I'll be using it to record the list of books I read in 2019. I'ts been several years since I tracked the titles I read, and I don't know how large the total will be. Maybe 100? It might get as high as 200 or 300 if I include graphic novels and picture books!
Honeycomb Decomposition Notebook: This was a sample from a trade show, I believe. When I started at the bookstore, I used this for taking notes because of the "bee" in our store's name. I started using it again recently for my work to-do list. It will soon be full; I think there are less than ten pages left.
Jane Eyre Journal: My personal to-do list. It's full of chores and tasks that are probably quite boring for other people to read, but if I didn't have a line reminding me that I need to get my glasses adjusted or return my mom's tupperware containers, I'd probably never do it.
2019 Planner: That's pretty self-explanatory. I didn't pick out a very pretty one this year, just the cheapest one at Walgreens. If I find myself using it faithfully, perhaps I'll upgrade, but I didn't want to make a large initial investment in case I stop using it in two weeks.
2018 Planner: I haven't finished transferring information from last year's planner (which was used very intermittently) but once I do this will be headed for the trash bin.
Budget Book: This blue notebook was a freebie at the 2017 Winter Institute in Minneapolis. We were meant to use it to take notes, but I always forgot it in my room and ended up bringing it back home with empty pages. I'm not using it to do monthly budget calculations and cashflow worksheets. Boring, but very useful.
