Don't take this wrong, but social skills are not overrated. In fact, based on my 31 years in education and my husband's 25 years in the software industry, I would say in the end, it's as important or more important than technical skills.
Believe me, I have not liked everyone I've worked with and often couldn't stand the endless talk of kids and babies, even when I had little kids. But, you can't be mean about it! No one wants to hear me talk endlessly about my bike, my average, where I rode last weekend. It's a fine line between "professional" friendliness and being friends. I really don't socialize with people from work anymore. I used to, but I find it's best to keep the spheres separate.
But, you have to be able to talk with people, customers (in my case, parents), and other professionals. It's hard to deliver bad news or give direction, but it's a skill that comes with practice.
I love talking to people in all situations, so advice from me probably means nothing. But a large part of my job as a teacher is teaching social skills. It's amazing to me what some families do not pass on to their kids...
