Labelling is something minds are good at doing and do all the time. In fact your mind is a labelling machine. It is helpful most of the time but is unhelpful when, as Barney says, you are comparing yourself in a way that makes you feel inferior, negatively affecting your performance, or you don't approach because (one of my favourites) 'she looks like a right stuck up bitch!'.

No. You have to see yourself as being on a level with people and that they want to be social just the same as you do. Which is really the way things are. As you start to go about with that mind-set you'll notice you start getting more positive feedback from people.
