GOING POSITIVE
I always wanted to look like the slim girls on TV even though I knew that it was impossible.I worried about my weight and tried every new diet I read about online.I tried no-fat，low-fat，5：2，only bananas，no bananas—I almost went bananas，too.
Then I read an article that said instead of asking “Am I fat？” I should be asking “Am I fit？” I had no idea a letter could make such a difference! Once I started thinking about fitness rather than weight，things began to change.Instead of saying “I want to lose three kilos”，I would say “I want to run two kilometres in eight minutes” or “I want to be able to do 30 push-ups”.Rather than cutting out the foods I enjoyed，I added healthy foods to my meals.I could still have a burger now and then，but I would add a salad or an apple.
Finally，I stopped comparing myself with actresses and models and looking for things that were wrong with my face or body.Instead，I made a list of the things I liked about myself.By being positive about myself and my body，I became both happier and healthier.
