Your life is a collection of dots. Each one holds a single day. 80 dots for a lifetime, 365 for a year. In each dot, there’s a piece of you. Write about your days, or simply watch them pass. One by one, they become your story. We often think we have more time than we do. But maybe not. See what remains— and feel today more deeply. Don’t just live the day. Leave your mark, one dot at a time.
