I went back to pen and paper tracking a couple of years ago after trying a dozen different apps. The apps felt like another thing demanding notifications, and I'd abandon them by February. With a printed sheet on the fridge, there's no login required, no push notifications, and it doesn't feel like a chore - it's just there. I grabbed a basic template, printed it on cardstock, laminated it, and used a dry-erase marker so I could reuse it. The trick is keeping it simple enough that you'll actually look at it.
The old templates from the 2000s aren't outdated so much as they're just straightforward. Some of them do pack in too many tracking categories, which defeats the purpose, but the core idea of a monthly grid with checkboxes works fine. You don't need anything fancy. I'd say grab one, print it out, and test it in January. If it sits there gathering dust by March, you'll know physical tracking isn't your style. But if you're the type who likes seeing progress accumulate on a tangible object, it's worth the paper and ink.
