For better or worse, a decision will be made soon. Be prepared to accept it and move forward.
You've got to be in it to win it. If you don't go to the party, you won't get an opportunity to dance. If you don't go to the meeting, you may miss an opportunity to network with other people. The truth is, showing up is half of the battle. If you don't go, you'll never know.
If you find yourself pretending to know what everyone else is talking about, it's time to educate yourself before things get embarrassing.
