I believe that personalities don’t actually exist—only reactions do.

 I believe that personalities don’t actually exist—only reactions do. Here’s what I mean: someone labeled “introverted” might have been “extroverted” instead, had they been born into a world so fascinating, so irresistibly engaging to them, that their inner world became the outer one. There’s also this: if a human lived not 100 but 1,000 years, would anything like a “personality” still remain? This suggests that what is called “personality” actually exists across infinite time—but since humans can only experience a narrow slice of it, they mistake that fragment for reality and give it the name “personality.” In that case, what does that label even signify? Merely a human being’s subjective response to the single possibility they happened to fall into, out of millions.
