I heard a story about an athlete and a fly:

He is a great billiards player and is very confident about winning this game. At the last moment, he only needed to score the last few balls to win the championship. He bent down and held the club carefully, locating the strength and direction of the shot. He thought that he must be the champion this time. Just then, a fly flew over for some reason. It was normal to have flies on a hot day. The fly landed on his hand and felt itchy, so he stopped and the fly flew away. Just when he was about to concentrate on getting ready to swat it. , the fly came again, and this time it landed on his forehead. He became irritable and went to swat the fly, but the fly ran away again.

He took a deep breath and prepared to hit the ball again. Oh my God! He found that the fly came back again and landed on a black ball like a ghost.

A nameless fire arose in his heart, and he raised his hand at the fly, meaning to let it get away quickly. The fly was indifferent to this. It flapped its wings twice and stayed still. He was furious, picked up the club and stabbed the fly.

The fly was frightened and flew away. But the club touched the black ball. According to the rules of the game, it was the opponent's turn to hit the ball. The opponent seized the opportunity to escape from death and scored all the goals he should hit in one go.

He failed to defend his title, and he hated that fly. It's a pity that he later suffered from depression and never had the chance to step onto the stage.

The story tells us:

An athlete with the ability to win the championship lost the championship trophy because he couldn't get past a fly during the game. It can be seen that mentality can often determine success or failure. A fly intertwined with his fate, perhaps by chance. The fly has flown away, who can he turn to for his pain and lessons? If he could have controlled his anger and waited for the fly, the ending of the story might have been rewritten.
