After graduation, I decided to take the gym a little more seriously. Accompanied by a friend, I began a regular routine of walking on the treadmill (踏车) or climbing the stair machine.

One day, he suggested that we take up a sport. Me? Sports? No way. I had spent my entire life as a person with no trace of athletic ability. I vetoed his idea.

Nevertheless, after a few weeks he convinced me to step onto an outdoor racquetball (短柄墙球) court. The first few “games” were quite funny. I hit the ball, sending it flying in every direction except for the direction that I had intended. Still, somehow, I managed to learn to play at a decent（相当不错的） skill level.

“We’re not getting enough exercise. We should play tennis instead,” my friend said.

“Tennis? I can’t play tennis! That involves real skills! I am not athletic; don’t you understand?” I firmly resisted his new attempt at ruining my life.

Nevertheless, weeks later, I found myself standing on a tennis court. The first few months • were quite painful. But one day, as the ball came flying toward me, my racket and the ball finally met in what tennis players refer to as the sweet spot最佳击球点. I had finally learned how to play tennis properly! Tennis would eventually become one of my favorite hobbies.

I learned an extremely valuable lesson during my journey toward mastering racquetball and tennis: I can do whatever I want, only if I set my mind to it. I just need to put in the work, and the results will follow. Had I not stepped outside of my comfort zone, I would have never discovered how much I enjoyed tennis. When I found the sweet spot in my tennis racket, I found the sweet spot in my life.
