Today I was browsing online on one of my favorite websites and found out it is "Happiness Happens Day"! What a lovely surprise.
According to the article, the "Secret Society of Happy People" who founded this day in 1999, originally called it "Admit You're Happy Day" with the goal of "spreading the joy of being happy, and to persuade people to look on the brighter side of life".
The purpose of our lives is to be happy. -Dalai Lama
