How have people kept from doing the "Oh 100 more today won't hurt." which turns in to "500 more once in a while is fine." which then leads to not tracking anymore because I don't want the "system" to tell me what to do. (Perhaps I know myself better than I thought.) Not sure if anyone has had that problem, but if you have, how have you kept from psyching yourself out?
I pull up my shirt and take a look at my gut when that happens. I am NOT kidding. It works for me because I get angry and more determined.
