Be coolheaded.
落ち着こう。
You don’t always have to rush even when everyone is in hurry.
“Shi-wasu” is another name for December in Japan. There are several theories as to the word “shi,” but one of them is to refer to a Buddhist monk. “Shi-wasu” means even a Buddhist monk, who is usually very calm, runs around because he is busy at the end of the year. This word also makes many Japanese believe that everyone is — and should be — busy in December.
It is one of the examples of collective beliefs in our society. It also shows that such collective beliefs often have no reasonable ground.
No matter what others believe or behave, don’t lose yourself. Stay calm and focused. You may notice that people are just running around or driving crazy with no reason.
