People like to feel safe and comfortable with their friends, and always ready to have fun. You want to give off the vibe that you’re comfortable with goofing around and also letting others have a good time. So chill out and you'll make everyone else chilled out, too.  Give people a quick compliment. This will show them that you care and that you’re paying attention. Laugh a lot. Have open, relaxed, body language. Show people that you’re up for anything. Try to loosen up as much as possible. If you're tense, your friends will be too. Cut loose! Make eye contact, put away your phone, and make people around you feel important. If you look distracted and like you have a million other things on your mind, then people won’t be able to let loose and have fun around you. Look at people with approval. Don’t make them think you’re condescending or judging them, or they’ll be much less likely to open up around you. If you're unafraid of how silly or ridiculous you look, people will want to hang around you. Here are some ways you can be a total goofball:  Do your best (or worst) impression of someone you all know, whether it’s a teacher or a coworker. Dance like a complete fool, pretending like you think you’re the best dancer ever. Sing the words to your favorite embarrassing song. Wear a ridiculous outfit, or a graphic tee with a silly message. Don’t be afraid to tell a corny joke or make a silly pun. If you've never done something before, that's a good reason to try it! Be spontaneous and try something new instead of making excuses. If you're the one coming up with the fun ideas to try new things, your friends will think you're fun to be around.  Say "yes" more. Instead of saying, “No, because…” try to embrace new challenges and try new things. Check out the last section for some ideas about fun things to do with your friends. Though we all have our bad days, you should focus on talking about the good things in your life and the things you have to look forward to instead of the annoying little things that upset you. This sets a positive tone for your social interactions and makes people want to be around you more.  If you catch yourself saying something negative, try to counter your comment with two positive comments. If the people around you are bummed out, then you should work on trying to cheer them up instead of sinking down to their level. You don’t have to completely fake it and plaster a fake smile on your face if you had a terrible day. However, you should make an effort to be more positive if you’re just mildly annoyed or if you know that whatever is bothering you isn’t a big deal.  If you're having a really bad day, just mention it and move forward with a positive comment. Say, "Today's been rough, but I'm staying positive!" In a group, try to make sure that most people like each other or at least get to know each other. Be a uniter, making the people around you bond and become closer with each other, even if it’s at your expense.  Be subtle about it. If you’re with two people who feel like they have nothing in common, bring up a mutual interest that can help them bond. If you have two friends who don’t really get along, mention nice things about one person to the other that will make them more likely to get along. Help people bond by suggesting fun activities that everyone can agree on, such as bowling or playing Red Rover. The more fun the activity, the better.

Summary:
Relax. Pay attention to your friends. Crack lots of jokes. Go on adventures. Keep things positive. Bring your friends together.
