I am 45 and terminally online, but I love paper, stationery and quality ink, pens and pencils. I take after my father, who also loved these things. I like the smell of old books, and it's a sensory pleasure to leaf through physical pages, rather than tap through a Kindle. I hate online planners.
So of course I have always had cute paper planners. The ones with "good" paper, for which I select "good" pens. I've abandoned the fountain pens of my youth for a more practical ink-ball Signo 0.38mm pen, in blue-black ink.
My current favorite planner is a Moleskine 3.5x5.5 pocket weekly that fits into my bag. I ordered a cute fabric cover for it on Etsy, and change out the planner every year.
My son seems to have inherited my love of paper planners. My daughter plans exclusively online, despite her love of drawing and appreciation for just the right paper texture. They scoff at my pen obsession, but I notice that my stash gets noticeably smaller every time they rifle through my pen drawer.
