Baby steps! You have a good start already and I think you're right to realize that pushing yourself to make ALL the changes you think you should do at the same time is really just setting yourself up for failure. I think just prioritizing them--maybe even having an actual list on the frig--of things that you are doing now and then maybe add one thing a week, or every other week. We're all making changes for life and we just have to make sure that our minds as well as our bodies adapt and it's not gonna be instantaneous!
Sometimes if it's eating 1 cookie instead of 3; or eating 3 instead of the whole bag
, ya know? Just finding places where we can put the brakes on and give ourselves permission for the little slip-ups--just to know that doesn't mean "oh shoot, I give up"--instead it's an opportunity to shake ourselves off and keep on going.
You go girl!
