Jack is a running enthusiast who trains every day in the hope of getting good results in the upcoming marathon. During a long-distance training run, Jack felt very tired, especially in the last kilometer, when he almost wanted to give up.

He stopped and sat on the side of the road, wondering if he could really finish the race. At this time, a strange runner passed by, saw Jack's condition, stopped and encouraged him, saying: "I have stopped here before. Giving up means losing opportunities. Keep going, the last kilometer is the moment when you can prove yourself the most."

Jack took a deep breath, stood up and continued to run. He told himself not to give up, just hold on a little bit longer. In the end, he surpassed his limit in the last kilometer and finished the race.

That day, Jack not only finished the race, but also gained the value of persistence and courage. He learned that no matter what difficulties he encountered, holding on to the last moment will always bring unexpected achievements.
