Spend three months traveling to seven different cities, and in each one, deliberately leave traces of yourself that will only make sense years later. Bury a time capsule in a park with a letter to your future self and GPS coordinates. Hide a book you’ve annotated heavily in a hostel library. Leave a sealed envelope with a bartender with instructions to open it in five years. Commission a small piece of art and donate it anonymously to a local gallery. Plant a tree with a plaque that has a cryptic message only you understand. Carve something subtle into a place that matters to you. The goal isn’t to be found by others—it’s to create a treasure map of your own past that you can return to. Then, ten years later, go back. Dig up the time capsule. Find the book. Return to the bar. See if the tree survived. You’re not visiting places—you’re visiting your former self, the person you were when you left these artifacts. Some will be gone. Some will have been discovered by strangers who have no idea what they mean. Some will be exactly where you left them, waiting. This is travel as temporal layering, as proof that you can haunt your own future, as evidence that the most profound travel experiences aren’t about discovering places but about discovering the distance between who you were and who you’ve become.
