I had an amazing time as a teenager because I spent all my time coding or with people I care about. The only negative consequences was that I got bad grades. I certainly don't regret getting bad grades.

I treasure the time as well as the moments. It's hard to get very close to people with just a memorable set of moments.

You don't have to be an extrovert to enjoy close personal relationships or have regrets about how much time you spent with loved ones when you had the chance.

I'm sure there are people who don't value people or relationships. If OP is one of them, I'm sure he'll disregard my advice categorically.
