A
It's 5：00 in the morning when the alarm (闹钟) rings in my ears. I roll out of bed and walk blindly through the dark into the bathroom. I turn on the light and put on my glasses. The house is still as I walk downstairs while my husband and three kids sleep peacefully. Usually I go for a long run, but today I choose my favorite exercise DVD, Insanity. Sweat pours down my face and into my eyes. My heart races as I face my body to finish each movement. As I am near the end of the exercise, I feel extremely tired, but a smile is on my face. It's not a smile because the DVD is over, but a smile of success from pushing my body to its extreme limit.
Some people enjoy shopping, smoking, food, work, or even chocolate. But I need exercise to get through each day. Some shake heads when they see me run through the town. Others get hurt when I refuse to try just one bite of their grandmother's chocolate cake. They raise their eyebrows, surprised by my “no thank you，” or by my choice to have a salad. Over the years, I have learned it's okay to just say “no.” I shouldn't feel sorry for refusing food that I don't want to eat.
So what drives me to roll out of bed at 5：00 a．m.? What gives me the reason to just say “no” to ice cream? Commitment. A commitment to change my life with a way that reduces daily anxiety, increases selfconfidence and energy, extends life and above all improves my body shape. This is the point where a smile appears on my face as I look at myself in the mirror or try on my favorite pair of jeans that now fit just right. It's through commitment and sweat that I can make a difference within myself inside and out.
