Well, how have you done this first month of the year in keeping with resolutions? Are you using any tools to assist you to stay accountable? If you are, hopefully, it's with a great attitude behind it rather than letting it frustrate you: journal whether you track it on your phone, computer, or a notebook; a scale, not to be obsessed but to help motivate your plans for the day, a friend to urge you on in sticking with the plan, etc. If it didn't go as plan, dust yourself off and get started again. Don't stress over it...which isn't beneficial.
