Let’s say that Jane is shy. Jane is told that she needs to meet people so she should go to the party that’s happening, walk up to the first person she sees and introduce herself.
She thinks to herself, “I should try to be cheerful and likable”. So she puts on very bright clothing and thick, colorful makeup. At the party, she goes to each person with the biggest smile and the largest eyes she can manage and makes sure - not letting anyone else talk - to tell them about herself, about how she was forced to come to the party, how people are always afraid of her, and so on. She’s trying to make friends and the important part of friends is that you know and understand each other.
And to the people that meet her, she’s a crazy looking girl who walks around like a robot, shouting at each person she meets, the entire tale of her life of craziness. They’re obviously disconcerted, and she can tell that.
Jane goes back to being shy. No progress.
Except, let’s say that instead of going back to being shy and avoiding parties, Jane says, “Okay, clearly I did it wrong. I’m shy, that’s too extreme a version of sociability. Tonight, I wasn’t shy and people acted like I was jumping on their feet. Maybe that was too much? Next time, I should try to find something between those two or ask someone to go with me, who knows how to socialize, to tell me when I’m going too far or not far enough.”
Maybe it’s not aspergers or whatever all else, maybe it’s a matter that hitting the right balance is a skill and, like any skill, it can help to receive instruction and for you to calmly review the output, hypothesize, and go out to test your theories.
But, likewise, if Jane was to ask someone to help her and, rather than treating it like a class, she simply, blindly does what the instructor tells her to do - telling herself the whole time that she’s unable to learn this skill and unfit for the purpose. She’s not going to try learning the skill. She’ll do good while the instructor is puppeting her actions. And when the instructor leaves, she’ll go back to being horrible.
Even with a teacher, you have to be actively learning; trying to figure out what the rules are that make you decide one thing in a situation and another thing in a similar situation; trying to figure out the underlying logic so you can apply it to other situations; asking questions to narrow in on answers; and continuing to think about it even after the class is finished and following up with more questions.
If you believe that you can learn, you have good nutrition and sleep, put yourself into learning scenarios, take time to calmly reflect and hypothesize, perform peer reviews, and keep repeating the process, then you can get there.
