I have just read something almost the same in a book about the triple crown winner American Pharoh, (I like horses). His jockey, during a difficult period in his own life, happened to visit the oncology section of a children's hospital where the children were in various stages of their treatment. Some with no hair, others at difficult stages of chemo, and of course, not all would live but all were dealing well with their situation and were even happy. He was moved to tears and began donating a portion of his earnings to the hospital.
Often we are so involved in our own lives and the narrow focus that involvement produces,we fail to see how fortunate we have been.
