My first assistant-coaching job in football was at William & Mary in 1961. The pay wasn't much, so to get $300 more per year, I agreed to coach the golf team. I didn't even know how to keep score, and really, my main job was not to wreck the van on the way to tournaments.
So many times people are afraid of competition, when it should bring out the best in us. We all have talents and abilities, so why be intimidated by other people's skills?
