What new activities have you all been meaning to start?

I told myself that after the last semester, I would not only build something of a routine but would also build a routine that consists of hobbies. Volunteering again as a listener on 7 Cups is one hobby I started again, but I'd like to try something else as well. I'm considering running as well or at the very least walking haha. I'd like at least one more activity to try out and establish as a part of my routine. Building this routine and building habits is something I've struggled with in the past, so I'm wondering how I can improve on that. On the subject of improvement, does anyone have any new year's resolutions that concern hobbies? I'd love to hear :)
