[pullquote]The hardest part of weight loss is not the exercise or nutrition, it is motivating you mind to make a change.[/pullquote] The odds are that this is not the first time you have tried to lose weight.  You have decided to become healthier in the past and failed miserably.  You own self-confidence, or lack thereof is a serious obstacle to success.  Notice the changes and celebrate your success even if it is a small one.  The more confident you become, the more likely you will reach your goal.  

Unfortunately, there is not magic to being successful.  Eventually, we all have our health fade, but we can extend our own healthy by making good decisions.  All of the excuses in the world will not help you reach your goal, but if you are determined, you can maximize your success.
