What it means is if you're a shy/socially anxious person (AS or not), don't try to be something you're not. Show the other people that you're a shy person.
At the same time, you have to still make a little effort. So be your shy self, but show that you're friendly and positive too. Smile, make eye contact, and speak little and often. Don't overdo it, otherwise you will end up saying the wrong things and people start to judge you. So just be casual. Try to relax. Don't be ashamed of being shy. Just train yourself to be friendly in a shy way, so that people will know that you're just shy, instead of mistaking you for unfriendly or weird or snobby, etc.
I know it's easier said than done. But that is what people mean when they say be yourself.
I think you're on to the right idea. I would understand "be yourself" to mean (at least implicitly), "be your
best self." My best self isn't rude, angry, selfish, etc. We all have those negative traits to some degree. Rather, the idea is that we shouldn't try to pretend to be someone that we're not. Be you, but don't seek to be the worst you possible!
