Turn on music and dance like wild. Let your hair down once in a while. Go back to the days of wild child hood. Close the door of your room, turn on your sound system to the highest volume possible (but a little lower than the level at which your neighbors start to complain) and then do the wackiest dance that you can think of. Jump on your bed and jump off it again.
Roll all over the floor. Pretend that you are Michael Jackson or Madonna (you will never see them keeping still) and do ever boogie move that you know.
