Maybe I didn't explain myself well enough, but I get along with other people very well. People like being around me for various reasons. Don't get me wrong - I am fully aware that there is much more to life than intellectual stimulation and in no way do I base my relationships with people on this idea alone. I'm just talking about one outcome of managing my relationship with others, and I would like to find out how many other people have gone through this (or are going through this) and how they deal with it. I find that self-improvement is one of the first steps in managing relations with others. Because at the end of the day, it is my problem, not theirs.
It's difficult to convey your precise meaning when it comes to interpersonal relationships. You can try very hard to explain what you mean but there will invariably be some ambiguity (it took me a few days to figure out how I should verbalize this to HN - in the end I decided to avoid analysis-paralysis). In many cases, the best one can do is hope that what you say strikes a chord with people in similar situations (hence the opening and closing sentences). That more people are commenting on individual pieces of my post rather than sharing there own experiences could be an indication that there aren't many people that can relate to this.
Whatever the case, I am grateful for the responses.
