I was introverted my entire life. I enjoyed it. I never really needed any contact with others except for a small circle of people and that too quite infrequently. I definitely recharge by being alone. Sitting in front of my favorite book, listening to music, watching a movie... doing all of these activities alone were something I always looked forward to. Walking along the beach coast, driving a motorcycle all alone were some of my most memorable activities.
Then.
I got into a relationship briefly for around 6 months. She was extroverted. After 6 months I slowly became gregarious. I enjoyed being around people and going out. I enjoyed building a community of people around me. My entire personality changed. Those who knew me from years back were surprised by my transformation. Previously, I wouldn't say much but now I can talk quite a bit. Its night and day.
The problem with labeling oneself is that it becomes a self-fulfilling prophecy. It becomes your identity and you start putting limitations on yourself.
My life was good as an introvert but it was great when I became outgoing.
Aaron Swartz had a similar experience.
" I believe fervently that intelligence can change and that talents can be learned. Indeed, I’d say I’m almost pathologically growth mindset. But even I began to notice there are some things I have a fixed mindset about.
For example, I used to think I was introverted. Everyone had always told me that you were either an extroverted person or an introverted person. From a young age, I was quite shy and bookish, so it seemed obvious: I was an introvert.
But as I’ve grown, I’ve found that’s hardly the end of the story. I’ve started to get good at leading a conversation or cracking people up with a joke. I like telling stories at a party a story or buzzing about a room saying ‘hi’ to people. I get a rush from it! Sure, I’m still not the most party-oriented person I know, but I no longer think we fit into any neat introversion/extroversion buckets."
