Compassion is sometimes the fatal capacity for feeling what it is like to live inside somebody else's skin. It is the knowledge that there can never really be any peace and joy for me until there is peace and joy finally for you too.
I've run the Boston Marathon 6 times before. I think the best aspects of the marathon are the beautiful changes of the scenery along the route and the warmth of the people's support. I feel happier every time I enter this marathon.
