I probably never need to buy another pen again, but er, I like having them around. See also notebooks, postcards, and other stationery. I am slowly collecting all the stationery of different types together as part of the decluttering progress around the house, eventually I will have it all in one place and then it will be very easy to remind myself that I don't need to buy anything new.

I do take a lot of handwritten notes if I want to remember stuff - for some reason writing the notes by hand seems to help fix things in my head. I did attempt formal bullet-journalling for a while but I mostly default back to "take notes, make lists" in whatever notebook is at hand.
