It works, but it's incredibly exhausting and not fun at all, so why bother?
I'm pretty good at socializing when I need to. I'll still most likely be wishing throughout that I was out eating dinner or having a beer at a brewery by myself with a good book or HN on my eInk tablet. Being by myself is extremely restorative and makes me happy.
I think this is what having an introverted personality is like.
I think it is easier for introvertes to gain extrovertion skill (clear benefits) than extroverts to gain introversion skills (benefits of being alone is not that obvious)
