     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 force

my body to finish each movement.As I 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.
