I don't doubt that socializing not only makes you a more rounded person, but is necessary as well. However, I'd bet you anything I'm in a different league compared to you when you were 29, because I spent most of my 20's learning and coding (about 50K LOC/year on average across 20 languages.) There's no substitute for putting in the time. However, who I was permitted me to make those choices while most of my peers made choices more similar to yours. So in a sense, there is a very real effect that's out of your control and probably goes back to your childhood.
