When you say that it pays off, is the main benefit just the pleasure you get from having lots of friends and social interactions, or are there actually substantial tangible benefits? Do you think you could reproduce all the tangible benefits with an extra $10K/year of income, or is it worth a lot more than that? I am curious because I have often felt like people who are good with people and know a lot of people should have a substantial advantage over someone like me, who is terrible with people. But then in practice I don't really see it.
