make the world a better place." I love running to this song by Vitamin C. But the other day, when temperatures reached 90 and the humidity was thick I tried a simple experiment. Rocking out to Italian hip hop, I was still struggling, my legs were heavy and I was not a happy camper. But I started to smile as I was climbing a hill, a shit-eating grin, and probably looked a little strange, but that smile was enough to shift my attitude and I kicked asphalt. I started to smile widely as I prepared for a sprint. The heat no longer affected me. It was magic, but it was just a smile.
