How? Plain simple!
every day submit a picture of what made you happy!
It can be anything from a meet-up with a friend to a very tasty cake in the nearby coffee place, from a feeling of being at home after a hard day to a favor you didto a stranger.
#100happyday challenge is for you - not for anyone else.
It is not a happiness competition or a showing off contest. If you try to please / make others jealous via your pictures - you lose without even starting. Same goes for cheating.
