I spent most of my time as a kid screwing around with computers and other whatsits, so I was really withdrawn and socially awkward after high school, and gave off the kind of accidental creeper aura that people here are talking about. (A mix of shyness, over-sharing, nonexistent small talk, and bad body language.)
Then I took a break from the tech industry for a while and ended up getting a job as a climbing instructor. It was an amazing change in a short period of time. I learned how to socialize quickly and easily with people I'd never met before, went out for beers, learned how to show people that they could trust me with their safety or their kid's safety really fast (because kids' birthday parties were a big revenue stream...).
Any kind of job or hobby that requires you to be social to do well at it should work just fine. (Retail and food service don't count.)
I'm sure there are people who are so naturally awkward that this is useless advice, but I suspect there are far more people who could benefit from spending more time around people than they do around electronics.
