Imagine you are running a marathon. Each time you are close to the finish life, it moves feet ahead. You continue running and realize that it had moved 100 feet. This time as soon you are about to reach the next finish line, it moves again. You get angry and frustrated but keep running and this time you realized that it had moved 500 feet. You keep going and the finish line keeps moving ahead.
Thing to be happy about – You have hope that there is a finish line.
