Extroverts bring energy, excitement and connection to the world. Introverts bring depth, thoughtfulness and introspection.
This above is a big takeaway for me.
And I agree, we can try to adapt but we don't completely transform. It's never a wrong thing or disadvantage to be an introvert. There are many goodness to it that people don't get to realise. It's better one holds to their true nature rather than try to adapt because of the words of others. Because like you said, you'll never completely transform into what you're not, and that will be a daily burden.
