Unfortunately for the people who "can't" make conversation - it's pretty much essential for social interaction, be that at work, at home, with your family, finding a partner.....
If you cannot (will not) make basic conversation, chit chat, small talk, whatever you want to call it, the chances are that you are going to have a very solitary existence and probably fail to make any real career progress.
Of course if you are happy with that then no worries.
I now expect to receive a barrage of responses from people who are unable to hold a normal conversion yet somehow claim to have fantastic lives filled with glorious and rewarding interactions.
I agree, I learnt that lesson in my teens and if I stayed in my comfort zone, shying away from social interaction then I wouldnt be where I am right now in life. I'm still working on my social skills day by day and I've made some great achievements in life because of it.
To some of the posters on here, if you like being alone and happy with that then suite yourself but don't complain when you don't get certain opportunities given to you or others succeed in life as you don't.
I had the same conversation with my best friend who was upset he didn't get promoted to supervisor in his job and they picked someone else who had been there half the time as him. I told him straight because he has crap social skills, is not a people person and would not be seen as a leader. He only had himself to blame as from the day we left high school, he went to work, came home and sat in front of the TV for the rest of the night. While the rest of us was out having fun, doing whatever, experiencing life.
Us as a human race are designed to socially interact with each other, not to be locked away in the corner and shy away from everyone. Many on here will argue with that and say "I don't to have make friends, talk to people, do what society expects me to do, blah, blah, blah" Well it's human nature and you cant argue with that.
As I said in the relationship thread, it's a common theme men being alone, not having many, if any friends at all. Yet most women keep all their friends for years and don't have that problem. It becomes clear after a break up when the man is running around clueless alone while their ex is out partying with their friends. Why is that?
Anyway, back on topic, you could do what I did last year and join a language class

Not only will you meet people, you will be forced to talk to them while learning a new skill, speaking another language which will benefit you in life.
