Ha, just laughed it off and kept things moving.

mostly people within 5 miles of me" is the whole story right there. Google ads are for people who already know they want a thing and are searching for it, but half the time they're three towns over or just price shopping. Facebook just dumps your face and your shop on people sitting on their couch two streets away. It's the same reason a church pancake breakfast does better with a sign on the corner than a listing in the paper. You're not selling a product people hunt for, you're selling "hey, that place looks good, I should finally get my dog groomed." That's a nudge, not a search. Your keywords were probably fine, the whole setup was just pointed at the wrong kind of person.

Eight years is a long time to be doing something "wrong" and still getting something out of it. The original bujo method from Ryder Carroll actually started as a way for him to deal with his ADHD, and people forget he says to make it work for you, not the other way around. A to-do list that you hate looking at is just a chore, but a book you actually open every day for 8 years clearly did something for you. Maybe the "supposed to" part is the real problem here, not your habit.
