Here's a thing I started in late 2025, and which I will continue this year. A small glass jar, and a big bag of colorful wooden beads. Every day I chuck in approximately one bead per "activity".
White for chores, yellow for studies, red for sports, orange for culture, purple for social, turquoise for hobbies.
It visualizes the accumulation of spent time in a very nice way, without being overwhelming. My #adhd seems to like it for sure. Putting a bead in is a small dopamine hit, I guess?
