The same way you would get better at programming: do the thing you want to improve more than you do now. Be willing to suck and be uncomfortable, and know that you'll get better through experience. Whatever activity you decide to practice, it's just a vehicle and a detail. Also recognize that there's nothing wrong with being an introvert, and nothing wrong with having a smaller circle than some others. We're biased toward extroverts because we're always aware of them, they're self advertising. Certainly if you want more social connection, make that happen, but do it in a way that you're comfortable with and that actually does you good. There's never any need for you to be the life of the party, but it's great to enjoy the party.
