A friend of mine on the spectrum recommended "The Tao of Badass" to me once, he tried to have some conversations on the bus after reading it, he said it worked for him, but still tired him out, he just didn't care. Makes smile, I'm sorry. I have no idea how it is, I was born with the skills, apparently.
FYI, I find this friend to be a fascinating person and a good friend. He hates change, he still lives with his parents pushing 40, but he is so real, so genuine, it's all I want in a friend. He'll never ask about my weekend, and when he does I feel it's fake (applying tricks from Tao of badass), he'll ask what my favorite thing was yesterday or how something makes me feel :D. But we can have passionate discussions about sci-fi or philosophy. He said he was called a high functioning autistic person, I joke that this means he is almost human. I got to know him at work, he could be exhausting, standing at my desk for literal hours asking questions. But I felt that I was a poor scientist if I couldn't answer them or explain why I couldn't answer them. He deeply appreciated that.
He works somewhere else now, I send him a message every now and them. I invited him to meet each other some time back. It was fun, he'll never contact me, but I don't mind.
