Lots of things, but so you could toggle them off (most of them) when creating the world so ppls wont say how much they dislike update what added something.
Just find a good friend (like i did) with which you can act as you like. Let your inner "YOU" out, do what you want, where you want and say what you want.
I was very shy too. im 17. Im not afraid of girls anymore . Just find a friends who has girl friends (not girlfriends, but female friends), and try to befriend some of them, teach yourself to talk with girls. Then befriend Her, after that try to get closer and closer to her, until she likes you like you do. (soz if my English is bad, havent used it for a bit)
