Great Sharing! What keep me motivated for keep on taking good and unique photo for people or my client, is as a wedding photography, sometime when you get to bumped into your ex-client after few years and they're still very appreciated for what you did for them, since you're their wedding photographer that time by helping them to catching the most important and wonderful moment once in a life in their wedding ceremony, their smile on the face will never be faded away!!
As I do agree #Photographer is some sort of Magician that can freezed your youth and happiness moment forever in your eyes while you looking back to the photos. :)
