A sales master is about to bid farewell to his sales career. On this day, he made his final speech in a venue.
   There was no shortage of seats in the venue, and everyone was waiting eagerly. The curtain slowly opened, and it was found that a huge iron ball was hanging in the middle of the stage. An old man came out in warm applause and stood beside the iron ball.
   People looked at him in surprise, not knowing what he was going to do.
   At this time, the two staff members came up with a big hammer. The host said to the audience, “Please have two strong people come to the stage.” Many young people stood up, and in the blink of an eye, two movements had quickly rushed to the stage.
  The old man said, “Please hit the dangling iron ball with a sledgehammer until you swing it up.”
  A young man pulled away and lifted the sledgehammer to hit the iron ball. After a loud bang, the ball didn’t move. He smashed them one after another, and he soon gasped for breath. Another young man did not show weakness, and took a big hammer to smash the ball, but the iron ball remained motionless. The two young men stepped down from the stage in despair.
  Under everyone’s gaze, the old man slowly took out a small hammer from his pocket and faced the big iron ball, knocked “boom”, paused, and knocked “boom” again. People looked at him strangely.
   Ten minutes passed and there was a riot in the venue. Twenty minutes passed, and some people simply scolded. The old man didn’t seem to hear what people were yelling at all, but he was still knocking slowly. At this time, some people had left suddenly, and large vacancies appeared on the venue.
  More than forty minutes passed. Suddenly, a woman sitting in front screamed: “The ball is moving!” In a short time, there was no sound in the hall, and everyone looked at the huge iron ball.
   Sure enough, the iron ball moved with a small swing! And the old man, still hammering with a hammer.
  The hanging ball swings higher and higher in the old man’s beating, and it strongly shakes everyone present. Finally, a burst of applause broke out in the venue. In applause, the old man turned around and slowly thrust the hammer into his pocket.
   The elderly gently faces the audience and slowly says: “On the road of life, if you have no patience to wait for the success to come, then you have to use your life to face failure.”
