In volleyball the term is Game, Set, Match. It’s referring to the game being over, someone wins, someone loses.
Your mind is the same way, once you make a decision the game is over. There is a winner and a loser. When you make a decision do you win more than you lose or lose more than you win?
The greatest thing about life is that the whole thing is played out in 5 inches, the 5 inches between your ears. The worse thing about life is that the whole thing is played out in the same 5 inches. You’ll win or lose based on your own decisions.
Anytime I am frustrated with my current situation I look at the decisions I have made to put me there. I evaluate and change. After all, doing the same thing over and over expecting different results is the definition of insanity.
