I went for a run this morning. I had some tendonitis, as well as some hip pain. On another morning, I would have felt discouraged by the the vicissitudes of an aging body that does not respond the way it used to.
But today, I thought of all those paralympians. My tendonitis and stiff joints are nothing in comparison to what they overcome very day: I imagined one of them next to me smiling, and it gave me tremendous strength and motivation to complete my run.
