George Sheehan liked to say when he borrowed lines from other great thinkers, "We stand on the shoulders of giants." My take is that we run beside and behind these people. They set our pace, leading us to places we couldn't have gone by ourselves. People stories have always been my favorite type to read. They give life to the times and techniques. They inspire as well as inform. A gap in my book writing, now about to be closed, was not giving proper credit and enough thanks to the people who were with me on every mile run and every line typed. I call them my pacesetters in this book with that same name.
