New here, week one, and an old calendar made me pause

Hi all, I'm brand new and only on my first week. I don't have a big story yet. I was cleaning out my phone calendar and saw an appointment from 2019 that I'd forgotten, and it hit me how long I've been putting off asking for help. This week I've just been trying to drink water with meals and take a short walk after dinner, nothing fancy. I ate half a burrito bowl last night and actually stopped when I was full, which felt strange but good. I'm nervous about overthinking every little sensation and becoming annoying. For people further along, what's one small habit you wish you'd set in week one? Sorry if this is a silly question. Thanks for having me.
