When I was s horse-crazy young girl whose family lacked the money for horses, my only option was to ride at this crazy non-profit run by a retired army colonel. Many stories I could tell! But he had a motto that always works for me when I think of defining success. "Ride hard, shoot straight, and live so you can look anyone in the eye." I find that when I can look back on a day, or a year, or a life where I did that - well it feels like success to me.
