"すべての本当の男の中には遊びたがっている子供が隠れている"
— Friedrich Nietzsche
Simplified Meaning:
Even when someone grows up and becomes an adult, there's still a part of them that enjoys having fun and being playful like a child. Think about how parents who are very serious at work can still laugh and play games with their kids at home. This shows that no matter how old or responsible a person is, they still have an inner desire for fun and joy. For example, a successful businessperson might seem all about work during the day, but on weekends, they might enjoy playful activities like playing a sport, getting together with friends for a fun outing, or even playing video games. This playful side is important because it brings happiness and helps balance the seriousness of adult life. So, it's good to remember to let yourself have fun and not always be too serious.
