On the far right side bar I've posted some books I hope will inspire you. You'll notice that not all of them are diet books. Some are tomes like Jack Canfield's The Success Principles(TM): How to Get from Where You Are to Where You Want to Be, which can help you with personal and professional hoals. (It's a long book, so you may want to borrow the condensed version on CD from the library before you decide if it's right for you.)
We can be on the best diet plan for us, work with wonderful diet conselors and personal trainers, and have a supportive family and coworkers. Yet we fail or have set backs because what our minds are telling us - those icky, negative thoughts that say we're failures so what's the point in adopting a healthy lifestyle?
