This doesn't mean you should be completely fake. It just means you should be absorbed in what you're doing instead of always wanting to be doing something "cooler" or "better."

If you want to be cool and popular, then you can't look desperate, or like you're always trying to hang out with the cool kids or waiting for people to come up to you. If you act like the life of the party, people will think you are. Even if you're at the party and are talking to someone who you don't really like so much, if you try to make the most of the conversation, laugh, and look like you're having a great time, then people will think, there's a person who is always having an awesome time, and they'll want to come up to you, too.
