For many years, I was convinced that my suffering was due to my size. I believed that when the weight disappeared, it would take old wounds, hurts, and rejections with it.

Many weight – conscious people also mistakenly believe that changing our bodies will fix everything. Perhaps our worst mistake is believing that being thin equals being loved, being special, and being cherished. We fantasize（梦想）about what it will be like when we reach the long – awaited goal. We work very hard to realize this dream. Then, at last, we find ourselves there.

But we often gain back what we have lost. Even so, we continue to believe that next time it will be different. Next time, we will keep it off. Next time, being thin will finally fulfill its promise of everlasting happiness, self–worth, and, of course, love.

It took me a long while to realize that there was something more for me to learn about beauty. Beauty standards vary with culture. In Samoa a woman is not considered attractive unless she weighs more than 200 pounds. More importantly, if it’s happiness that we want, why not put our energy there rather than on the size of our body? Why not look inside? Many of us work hard to change our body, but in vain. We have to find a way to live comfortable inside our body and make friends with and cherish ourselves. When we change our attitudes toward ourselves, the whole world changes.
