I love seeing the scale dip down into a new number! That, for me, usually means that the body is ready to be at a new weight and if I behave well, I'll get there
I found that this thread helps a lot with accountability. I have to admit to being discouraged and not wanting to post when the scale goes up. But I realize that if I stop and lose the momentum, it'll be even harder to get back on the wagon. So I told myself to keep on checking in even if it's just a small weight update
