I've never been given an ASD diagnosis, but have wondered if I was on the spectrum. Regardless, I've struggled with reading faces, and generally just being weird/awkward in social situations. One thing that really helped me though was my first job where I worked retail selling computers. Initially the hardest part was approaching people. Once I approached someone and they seemed interested in a PC or Laptop it was easy, I just had to talk to them about one of my favorite topics (computers). I ended up being one of the top sales associates, and this gave me confidence to be more outgoing and social outside of work.
