Want to have fun? I know you do or else you would not be reading this. It's simple really. The first thing you must remember is that having fun isn't nessecarilly about jumping out of a plain or dancing with an exotic stranger. Although those two options are definetly enticing. Fun is too general for that and everyone is too different. The first thing you have to do is figure out what tickles your so called fancy.
Step2
Next, make a list of those things. If your having trouble figuring that out. Try and recall all the times in your life where you have been obliviously happy. If that hasn't happened since childhood, that is okay. still try and remember what made you the happiest. Now if you said building sand castles then you know that being creative and being outdoors are two of the things you really enjoy. If you said, making videos with your friends, than that would mean you like attention and drama. Get the picture?
Step3
Now, the last step is tricky. You ready for this? Go do it or try something new like it. Take a risk, go on a date. Try stand up comedy or take up painting. You have nothing to lose except the boredom you are obviously experiencing in life. SO GO HAVE SOME FUN.
