Hi
It sounds as if you already have an interest in people, by asking how to be motivated expresses an interest.
I've also had many difficulties relating to others face to face. No matter how much I want to, it's still difficult.
You mention your fears of socializing because of self-conciousness. I wonder if social phobia is a better description of how you feel. Anti social refers to someone against society. Maybe you are against it because of your fear.
My social fears led me to dislike society too, but underneath that, was an intense wanting to belong. I try not to project my fears on others. It isn't fair to them, and doesn't solve the problem.
I'm still working on this too. I think getting a clear picture of what makes you fearful will give you a list of fears to address. Then, one by one, re-evaluate the validity of your beliefs surrounding the fear. Many times our perceptions about ourselves are far from what others see.
Another thing to consider is, do you really have an interest in the current conversation? Just because everyone else seems to be enjoying it, doesn't mean you have to. We are all unique. What interests you may not interest others and vice versa. It's really a matter of finding those who share your interests. I often feel that I am the outsider, not really interested in the popular subjects. For many years it's made me feel that something must be wrong with me. But the truth is, I have my own way of looking at and dealing with things. I need to honor that. Trying to conform to everyone else "kills" the real me. We all have a gift to give the world. Being someone other than ourselves prevents us from giving it. Believe in yourself. It may be very hard right now, but we are all a work in progress. When you think about people throughout history who have made major changes to the world, they all thought for themselves. Maybe they were influenced by or studied under others, but, eventually, each struck out on their own, and "did it their way".
I have few friends and no girlfriend. I prefer the simplicity. I'm in control of my destiny and time. What I earn is mine. What I risk is mine. I have to answer to very few. (my boss, my teacher, myself) I actually ward people off. I can't find many that I feel comfortable with. Is that a reflection on them, or me? I think it's the latter. It's not that I feel "better" than anyone else, but less complicated. I'm not into "pop" stuff. I don't care about pop music, pop movies, pop past-times, pop culture, etc....... I have a different set of values. You have your own too. Find them, and treasure them

"This too shall pass...."
