After Eliud Kipchoge broke the world record and ran a marathon in under 2 hours, he said, “That was the best moment of my life.” That probably didn’t come as a surprise to him. It was a big goal that he had been working towards for a long time, so the fact that achieving that goal was the best moment of his life was probably to be expected.
Contrast that with winning the lottery. If that were the best moment of someone’s life, they would have arrived at it completely differently—by placing a bad bet and getting lucky.
It’s much easier to have the best moment of your life through hard work and things you can control than by wishing and hoping and waiting for the moon to fall in your lap.
