1. Keep that lip buttoned up!
OK, so you can bitch, whine, and moan to your closest friends and family (as long as they don’t overlap with your colleague group), but you don’t want to broadcast your discontent at work—maintaining even a modicum of positivity will make your day more pleasant. (Ever heard that smiling can actually make you happier?) And definitely don’t post "I hate my job" missives on social media. Facebook privacy settings are notoriously difficult to parse.
