"清教主义：挥之不去的恐惧是某个地方有人可能会快乐"

Simplified Meaning:

Puritanism is like being so strict and serious that you can't stand the idea of anyone having fun or enjoying themselves. Imagine a teacher who believes that children should always be studying and never playing. This teacher would get upset if they saw kids laughing and having a good time because they think happiness means they’re not working hard enough. Historical example: In the 1600s, the Puritans were very strict Christians who lived in America. They thought almost anything fun was sinful, so they banned activities like dancing and playing music because they believed these things led people away from God. In your life, this idea suggests being careful not to let your own strict views make you resent others for enjoying their lives. For example, if you have a demanding job and work all the time, don’t begrudge your friends if they take a break to go on vacation. Instead, try to find a balance so you can also have moments of happiness.
