@bloomer Nice to know somebody relates. As you say, extroversion isn´t special, and they also have flaws, but its hard to realize that sometimes. I think as long as one has a flawed perception of oneself, one will have a flawed perception of others. So the solution here is to work on ourselves, and it will translate to how we relate to others, I think.
When it comes to small talk, thanks for the advice you linked, but I personally think I´ve come to a point where listening to advice on how to socialize does more harm than good to me. Because it makes it seem like my problem is a lack of social skills, but I´ve realized that it´s rather a problem of fear. When I am relaxed I can small talk easily.
So I suggest you to ask yourself the same. Is the problem that you lack social skills and need to learn how to small talk better, or is it that you can small talk when relaxed, but fear gets in the way sometimes? Perhaps both, one can always improve social skills of course. But as of now, is your biggest obstacle fear/low self esteem instead of lack of social skills? If it is the case, you might have to reconsider how to go about your problem
Thank you for your kind words.
