I'm not an extrovert. Introversion itself was probably more of a euphemism that I used to rationalize something closer to social anxiety.
But I feel I'm better off now for doing what the article suggested, over the last 5-6 years. Doing so improved my knowledge, my empathy, grew my revenue, built larger professional networks, introduced me to hobby networks, and helped with better financial planning.
I even changed to the extent of actually looking forward to outreach activities that involve a lot of conversations. I find them very satisfying because they help me understand social realities and people better than social media and books and help me develop empathy.
I wouldn't say I'm now an extrovert. My personality still prefers a lot of alone time. There are times when I still don't feel like talking to anyone. But they're now for positive reasons like books to finish rather than negative reasons like social anxiety.
I now tend to see things like introversion and social anxiety as obstacles. One can rationalize them in many ways but they'll remain objective obstacles IMO.
Thank you for proving my point - for some reason you felt you have to explain how introversion is an „objective obstacle”.
