“There is a great difference between worry and concern. A worried person sees a problem, and a concerned person solves a problem.”
Come out of serious mode for a day and let yourself laugh. Sponsor a game night at your home and invite some good friends over to play cards and nibble on snacks until midnight. This is a day to have fun, so let loose and be free to express yourself in the best way you see fit. Realize how much power you have in your jovial nature.
