I'm very introverted which, in the past, used to bug me because I felt like something was wrong with me. I kept feeling like I should try and be more social. But, a few years ago I took a Myer's Brigg personality test which categorized me as an INTJ. It was at that point I realized that, hey, the "way" I am is simply my personality type and not due to something being "wrong".
I genuinely enjoy my time alone and I've never felt lonely (don't have a girlfriend nor do I want one). I enjoy talking to people at work and we often go out for lunch or a movie but that's the extent of my desire to spend time with them. Most everyone likes me and I seriously doubt anyone thinks I'm an asperger weirdo.
