On Friday, I found out that I have only gained four pounds since the last time I went to the weight loss center, which was last year. I have celebrated for four days. I am all smiles and renewed energy, going out for long walks and doing yoga at 5 a.m., eating healthy foods, taking my vitamins again. I wonder what this says about my self-esteem and my perspective on what really matters. It's a measurement. Just four pounds, apparently, is what happiness weighs.
