The 'self' as defined by, say, interests is entirely circumstantial. It completely depends on input from others and what you are exposed to in the formative stages determines who "you" are. Take the same genetic combination and move it to the usa and you might get a football loving NT person, but in deep indigenous south America you get an expert spear-thrower, or adopt them into a family of engineers and you get a Trekkie, who then becomes the next engineer. We have some natural leanings, for example someone who is nearsighted is unlikely to excel at baseball, cricket, (spear throwing), etc. However put them with a rich family with access to an optometrist and lazer eye surgery and will be as if that little genetic variation never existed! You are an aspie or not because your parents are aspie or not, alternatively because you gestated in the presence of this or that local environmental factor that may or may not be present somewhere else. I'm not saying it's fate but more that the dice only role once and the rest of the game is played with that roll, and how it interacts with all the other rolls.
There are a finite number of possible personalities as there are only so many general attributes to be added or subtracted to the docket. You are born with natural tendencies, such as shyness, touch sensitivity, or alternatively high pain tolerance and lightning reflexes and clearheadedness. Your "self" is not truly unique, it is merely an amalgamation of the available inputs. Almost no one is truly unique except in how the collage of attributes is arranged. This does not mean that people are the same or even similar, but more that there are a finite number of archetypes that are available for you to occupy. This is necessary because it would be impossible to memorize interactions for an infinite number of possible personalities. Most people prefer to specialize in just a few archetypes and abhor or avoid all others (i.e. bullying, racism etc.) for simplicities sake.
Part of the reasons aspies have trouble socializing is they fail to fully incorperate a particular archetype and therefor there is, in fact, no knowable way to interact with them. It is impossible to know how to react to someone that you have never met before, understanding that someone really means some-archetype. EG looking at the "popular" crowd and the various subgroups beneath them you will find little or no variation between individuals. If you were to try and describe them you would find yourself in an infinite loop of repetition: X hair, Y eyes wearing a polo shirt and jeans. Plays A,B, and C sports.
My favorite analogy of this stems from a researcher analyzing the mating patterns of monarch butterflies. Monarch butterflies courtship rituals require the male to complete an intricate dance with the female, however this is not instinctual so much as cultural and the dance varies from clutch to clutch and when monarchs migrate they always breed in the place of their birth. The researcher was documenting the monarch population when he noticed a male monarch drift in from the west, clearly displaced. The male began attempting to court females. His dance had loops and swirls and dives and was beautifully acrobatic, but because it was not to the expectation of the females mid way through the dance when he was not in the required place they would lose interest and wander off. The male continued attempting to attract a mate but was not able to do so before the end of his short remaining lifespan and died before the day was out. This is how researchers discovered that even insects have learned behavior, culture, and ethnocentrism. The advantage to being human is self-awareness of the existence of these patterns and the ability to observe and learn from others who are more socially adept, or alternatively ask for directions back west.
My interpretation of this information is that it is better to make oneself more generic, but a specific kind of generic. Pick and archetype and stick with it. It doesn't have to be the main archetype or even a common one. But by creating a persona that conforms to a set of social norms that is applicable to multiple aspects of that collective 'self' strangers will have an easier time adapting to those first few interactions. As Shakespeare said(ish) 'all the world is a stage and we are just actors,' so stick to the script! More importantly realize even though there is a script, and no director to call cut and try the scene again.
