Where to begin?

Two days have passed since my social practice ended. These two days have been fulfilling, but also frustrating.

This social practice was a great success, achieving breakthroughs in various aspects. We felt our team operated efficiently, with each person having a clear role and fulfilling their responsibilities. Everyone was able to utilize their strengths and complement each other's weaknesses. The seven days in the countryside were fulfilling and enjoyable, even though conditions there weren't as good as at home.

The first thing I did upon returning was to get a good night's sleep, not because I couldn't sleep there. Sometimes, mental stress is more unbearable than muscle lactic acid. The day before I came back, Huang demonstrated hypnosis in our room, which suddenly gave me a strange feeling. We live in a wondrous world, where science still has so much to explore. Sometimes we can foresee the future, sometimes we can see the past. Some people live a life of smooth sailing, while others are burdened with tragic fates. In this wondrous universe, we are so insignificant. This point on the timeline may be our intersection; history won't remember it, yet we care so much.

Last night and this morning, the World Cup final kicked off. I watched most of the matches in this World Cup. My introduction to the World Cup was through my dad; I vividly remember that time in 1998 when he got up in the middle of the night to watch the game. After that, I rarely saw him watching football anymore. As people age, their interest in their hobbies gradually declines. Time is so cruel. I am growing up, while they are growing old.

There is always a trade-off between giving and receiving; how do I choose between them? What is it that I can't let go of?
