クールの賞味期限──沈黙はいつ価値を失うのか

In this episode, I discuss the hidden expiration date of being “cool.” Quietness can be seen as attractive when we are young, often mistaken for confidence, depth, or mystery. But as we grow older, the same silence can quickly turn into a weakness. What once looked cool may start to feel like a lack of opinions, poor communication skills, or emotional distance. I explain the difference between chosen silence and defensive silence, and why relying on quietness alone becomes risky over time. True long-term value comes not from silence, but from the ability to express ideas clearly when it truly matters.
