What’s one thing you force yourself (or recommend others) to do every single day, no matter what?

Whether it’s reading, meditating, journaling, making your bed, going for a walk, eating enough, listening to music, or creating—what’s your non-negotiable habit? Do you have a structured routine, or just fit things in when you can? How important is it to you?

TL;DR: If you had to pick ONE habit that you have to do every single day for the rest of your life, what would it be?

I’m really bad at sticking to a morning/night routine because I don’t have a solid one. Ideally, I’d wake up, open my curtains, mark the calendar, take my meds, and journal—then move on to breakfast and the gym. I also want to build systems to avoid being idle.

I’d love to steal some ideas—what works for you?
