It seems that once people reach their 30s, many think, "It's too late to start something now." There are also many who blame their age for their fear of new challenges, saying, "If I were in my 20s, I would have tried all sorts of things by now." In an era where we can expect an average lifespan of 120, I find myself wondering, aren't people in their 30s still just kids? Haha.
