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.

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.

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....
