I also disagree strongly with that. I live in Seattle (a city well known for being not social and welcoming - aka the seattle freeze), and didn't recover from being a shy introvert until around 30. The skills and mindset for human connection was hard for sure, but I found many pockets of really welcoming social environments around shared interests. My personal interests run to the outdoors, so for me it was hiking/biking/mountaineering/run clubs. However, groups and clubs around shared activities exist for almost any interest, and the whole point of them is to socialize and meet people! It DOES take some effort and discomfort, but it's not even close to "almost impossible".
