When Max Lucado participated in a half-Ironman triathlon, he experienced the negative power of complaint. He said, “After the 1.2-mile swim and the 56-mile bike ride, I didn’t have much energy left for the 13.1-mile run. Neither did the fellow jogging next to me. He said, ‘This stinks. This race is the dumbest decision I’ve ever made.’ I said, ‘Goodbye.’” Max knew that if he listened too long, he would start agreeing with him. So he said goodbye and kept running.
