To reign in hell is not better than to serve in heaven. To learn how to socialize is a slow process. Someone will have all the problem you describe, ie. making it worst, if he tries to solve everything and tries to be like everyone else.

I have the problem you describe. I know exactly what you are talking about, and you hit the nail on the head. However, I've improved. There's fewer social situation where I don't belong. More situations where I can feel confortable and "be myself". There's still a lot of other situation where the others instantly feel that I don't belong or that I can't relate, you learn how to see it. It is possible that I've improved as much as I can but I will continue to try to improve. I think that someone who is asocial shouldn't try too hard, it will most likely do more harm. The alternative, avoidance, is never acceptable because of the cognitive dissonances he would need to accept to make it work. He'd reign in hell, but it would his personal hell, he'd reign over nothing.

Improvement should not be made on social skills directly, for similar reasons you described, but on just being more interesting and available. Being more interesting by learning how to travel alone, to have a hobby, anything he is ready to do only for himself. Being more available to socialization(sometimes you can't avoid it) by being clean, by having and controlling welcoming spaces (his living room or his office, etc.), by being happy. He will attract people who wants to be with him, or not but at least he will be happy. To just abandon socialization as a complete solution just looks to me like a slow and coward suicide.

My opinion is that an asocial person should put himself in a situation where the view you expressed becomes irrelevant.
