I like this as a life lesson for all circumstances. I use it with my kids often. In the context of sport, don’t let the referee decide the result, means play so well that a few unfavourable calls won’t matter.
As a rugby coach of 13 year old boys, I have occasionally heard players, from both sides, comment on the reffing standard in a match. These types of comments can sometimes come from adults too when they are playing or watching sport.
My simple response to people is to play better and play harder. Outwork and outthink your opponent. Score many more points than the other team. Then, if a few calls don’t go your way, it won’t matter.
Play so well in every aspect of life that the ‘referee’ that observes your performance can only reward you with a win. Yes, it means practicing more and playing at a higher level at all times. That is fine, because excellence is a worthy habit to strive toward anyway.
Whether it is at work, in a relationship, driving your car, parking or paying bills, etc., don’t let things get so close that a third party can impact the outcome.
Train with enthusiasm and harder than you would play in a game. Then play the game so well that you win convincingly. Don’t let the referee decide the result.
