There's a difference between showing up...
...and MAKING AN ENTRANCE.
First impressions are kind of a big deal.
You don't want to be all shy and awkward.
Your arrival should turn heads...
...without being too over the top.
If necessary, take a moment to get it together.
Then slowly open the door and enter.
Maintain good posture. Walk with your head up, your shoulders down, and smile.
Just don't come off as arrogant.
And definitely don't put your head down, slouch, or try to make yourself invisible.
Instead of bolting for the warm safety of alcohol or food...
...calmly survey the room. Let people see you.
Try to introduce yourself to everyone...
...without being a total attention whore.
A sharp outfit always helps you feel more self-assured.
But avoid any clothing that's too gaudy.
Still anxious? Don't be! Remember, everyone else is probably just as nervous.
Most important, smile and be friendly and people will naturally be attracted to you.
Congrats! You've successfully made an entrance!
You can worry about your smooth exit later.
