What do all Olympic athletes have in common?
Answer: a “coach” they trust. And while there may be several they get counsel from, there is probably one person that is really the “coach.”
Their methods may differ, but behind every great athlete is usually an individual who has “coached” them to victory. Why does someone who is so gifted need someone behind them “coaching” them along? Ask the athlete and they will probably tell you their coach helps them bring out their best game.
