Let's take study as an example. A strong learning atmosphere can make people concentrate and immerse themselves in learning. Everybody be quiet, don't talk, and do your homework carefully. This is the mantra of high school teachers, and I believe everyone has heard of it. This sentence is not unreasonable.
Not everyone has a high degree of self-discipline. A large number of people will be lazy as long as their surroundings are slightly relaxed. It is human nature to love to play.
I just like a serious and tense working atmosphere, which will make me motivated and more efficient if I take it seriously. That's what it is for me anyway. Some people may like a relaxed and happy working atmosphere and think it is more suitable for them.
The relaxed and happy atmosphere is really good, which makes people feel very comfortable and will naturally work hard, but it is not suitable for people like me who like to play.
