Is someone different at age 18 or 60? I believe one stays the same.

The core of you stays the same

There's something both comforting and unsettling about this idea. We tell ourselves we're constantly evolving, reinventing ourselves with each decade—different jobs, different relationships, different versions on social media. Yet Miyazaki is pointing at something deeper: the core of who you are, the way you respond to the world, your fundamental nature, probably doesn't shift as much as you think.

Think about people you've known for decades. You can usually spot the thread running through them—the curious person at 20 is still curious at 50, just with more information. The impatient person finds new contexts for that impatience. We accumulate experience and hopefully wisdom, but the underlying texture of our personality, our temperament, the things that make us us, tend to persist stubbornly.

This matters because it can free you from two traps at once. It means you don't need to wait for some future version of yourself to finally be okay or finally figure it out—you're already essentially you. But it also means accepting yourself isn't abandoning growth; it's more like growing from a foundation that stays recognizably yours. The question shifts from "Who will I become?" to "Who am I becoming with the person I already am?"
