Building habits takes some effort. With physical activity walking is an excellent start, you also don't have to exert yourself to the point of fatigue to get benefit. You are probably more likely to repeat the effort if you don't overdo it. Just relax the mind and put one foot in front of the other.

That's great on the tobacco! I'm at the six-week mark for quitting smoking. Last year I felt like it had begun to impact my health so I had to cut it out. I've been using nicotine pouches

I don't feel any urge to smoke, though I'll be more confident when I have 6-months under my belt.

Unsolicited advice - we are on HIVE and we love to write and document things - don't let that be an excuse to not get in a walk or a ride. "I'm not going to have time to write this up here" shouldn't become an excuse not to get in some activity!

Congratulations on making changes, and being proactive about your health!
