Once an Introvert, always an Introvert?

I think I turned introvert around 9 aka puberty. Nothing shocking happened, thats just my programming.

I think that statement is for the most part correct. I think introverts may be able to acquire skills that allow them to adapt better in an extroverted world. However they will somewhat always remain introverts, and without practice, they lose these abilities, which extroverts naturally have. Speaking from my own personal experience, of course.
