Every day, another letter, written by you to yourself. But.. you are only aloud to read those letters exactly twenty years later. Not before, not later. It's a deal you made with yourself. Nobody know's about it but you. You could compare it to a diary. It's secret and you write. Everyday a new letter, put in an envelope and lay it down in a box with the date of writing and the date with opening on it.  These letters give you a reason to wait for something to happen. Waiting is your talent. While you write letters, a lot thing happen and change. Wanna know what? ;)
