In school, I wasn't anti-social. I wasn't mute. I wasn't shy. I was just quiet. I barely spoke to anyone during class, unless they spoke to me. I was there for the education, and got out as soon as I was permitted. I socialized when socialization was expected; in the halls, between classes, after school, at lockers, etc. and my extended communication was limited to people I were friends with.
I highly disagree that you can't make it far in life without strong social skills. You can't make it far in life without an education, point blank.
We had a program like this in our school for incoming freshman. We had it every month, during a gym period. It was stupid. I felt like I was in Kindergarden again, and I barely took the session at all seriously. Social skills are developed early on in life. No matter what you do later, you usually can't change their habits. Social skills aren't exactly something you can learn. It's something you pick up, and develop as an individually based on your past experiences.
