As soon as I started getting obsessive about setting goals, I ended up sabotaging myself and stalled, lol, but that's my personality! Do whatever works for you
I have the weight range where I can go back on the pill as a goal... But I want that so much I'm trying not to think about it, and I'm getting into that range now
That said, when I started out, before I got obsessive about it, my mini goals were 1lb each, and I've now hit 23 mini goals! Whatever keeps you going, even if it's just a daily goal of doing the best you can with what you have. Honestly, it all adds up! If you find you've lost 17lbs or whatever, and you like it, who cares if it's not a significant or rounded number? Reward yourself anyway and keep on keeping on!
