Of all the things to love about the Fitbit craze, the ability to challenge other users has to be the most entertaining.
If you're unfamiliar with this device, it's an electronic wristband that measures various aspects of a person's health: heart rate, sleep patterns, and perhaps most importantly, steps per day. 10,000+ steps is the ultimate healthy benchmark, so a little friendly competition is a great motivator.
A friend of mine recently became obsessed with beating her 7-year-old niece in a race to the 10,000 goal. When I told her this seemed like an impossible feat, given the fact that the little girl had the significant advantage of youth, my friend simply gave me a knowing look.
"Yes, but she also has a bedtime."
So that's how determination and craftiness beat boundless energy and enthusiasm. Play to your strengths, lady! And step to it.
