People are more interested in talking about themselves than others.

This is good because you can use this to start a conversation and get to know them more before you tell them anything much about yourself.

Telling others too much about yourself at the start leaves you vulnerable to having them trying to be who you want rather than who they are.

Every one to some degree has the same problem as you talking to others. Its a bit like dancing, practice makes for improvement so practice talking to others where it doesn't matter like at the check out at the supermarket.

Hi I like your brasses, are you afraid your pants will fall down
