For all its negative aspects, this restless spirit can, at times, be a blessing. It is the appetite for life that continues to keep one young and alive. It is the key to inspiration that fuels imagination and creativity. "Never satisfied!" Walter Matthau once described me to his wife, Carol. It was not meant as a compliment. But I take it as one. There is so much to be thankful for, and I am even thankful for my restless spirit.
