I’ve heard it so many times in movies.
A female character being concerned, at some point in the story line, to walk into a room…get ready for it….by…. herself *gasp*!! Unfortunately, I have seen the same situation in real-life.
Okay, I’ll be rid of the sarcasm.
What I’m trying to get at or am saying is that: walking into a room without a partner isn’t as horrible of an experience as it may seem. Sure it might be difficult at first, but take it step by step. Walk into the room with your lovely smile in hand, understand why you’re at the event and do whatever it is you need to do.
Think of walking into a room for a social event by yourself as a task. Set a goal and work towards accomplishing it. Obviously don’t get all serious and stuff–be open to experiencing everything around you but it helps to have a goal in mind.
The more you do this, the easier it will be to enter a room without feeling the need/comfort of someone else. Sooner or later, it won’t even be a issue and you’ll wonder why it even was in the first place.
Take it step by step–there are advantages in walking in a room as a free spirit
