not be such a push over

Out of the drunken confessions of co-workers, apparently a few of them think I’m outgoing!? Huh…weird, right?

I am so scared of everybody that people just think they can walk all over me. I don’t speak up until I am at a boiling point then things get ugly.

There are very few people that I really like and I don’t know what to do. How do I change my personality to a positive one that people will like??
