Sometimes a direct approach can be extremely effective. Do you have a message for the human beings of the future that you could capture in a short letter, a photograph accompanied by a message, a podcast or video? Do you have advice, an anecdote, a warning, a brief story about the past (and a comment on why this is worth remembering), or a plea? If so, capture your idea in a letter (500-1000 words), a single image accompanied by a message (maximum 250 words), a podcast (1-5 minutes in length), or a short video (1-5 minutes in length).
