It is all about Accountability

I need to be held accountable for my actions. I start a new diet maybe 40 times a year. Either I do well and then fall off the wagon after shortlived success and gain my weight back or I go on a diet, don't succeed and quit. Even if no one ever reads this, although an audience would be appreciated, I need to jot my days down for accountability. I would love some advice or encouraging words along the way so feel free. I love reading in my magazines these great life overhaul articles where someone is followed for a year and helped along the way by nutritionists, personal trainers, psychologists, etc. But I am just a regular person with none of those resources at my fingertips. I am just a 31 year old woman with a husband, preschooler, and faithful family dog. Oh, and about 50-60 pounds that shouldn't be tagging along...
