The Science of Happiness

Kate is a bright young woman with an intense focus on academics and a long-term goal of becoming a neuroscientist (神经系统科学家). Her path is charted very carefully each day according to schedule. She meets after school with the Brain Club, a group she started that discusses neuroscience and trades academic papers like baseball cards. It’s the kind of group you would never imagine in high school, which is mature beyond their years and led by their own initiative.

It would seem there was no room in Kate’s schedule for fun, let alone helping others. But then she found out about an elementary school hit hard by the pandemic, then inflation, and now a recession (衰退). It sits in the middle of a working-class neighborhood and most of parents were tired out by working physically demanding jobs from dawn to dark. Most families were doing the best but they could just put a few groceries on the table.

Halloween was approaching, and many of the families didn’t participate because they lacked costumes and couldn’t afford to give out candy themselves. So Kate called the headmaster of the elementary school. She was told the families wanted their kids to have fun on Halloween, but they also needed more books in the home.

So Kate went to work. She began with the Brain Club and then branched out to other clubs. They would sponsor a trick-or-treat event featuring games, candy and book giveaways. It was a huge organizational challenge—one that only a very organized person could handle.So Kate put her smarts to use. She arranged for groups of her fellows to decorate their cars and create games. She found a DJ and rounded up boxes of costumes for the kids. She even got the local police to decorate their cruiser (巡逻车). And she went to work getting kids books donated.
