Everything you're worried about will have an answer by the time this arrives.
Write a letter to yourself today. We print it, hold it for a year, and put it in the mail. You will have forgotten it. That is the whole point.
We do not read it, index it, or keep a copy. It prints once and the file is deleted.
Nothing to install, nothing to remember.
You write it today
Any length. Most people manage about four hundred words and then keep going.
It sits in a drawer
Printed within a day, sealed, filed by month. Physically, in Kansas City, in a metal cabinet.
It shows up
One year later, on an ordinary Tuesday, in a stack of bills. You will not see it coming.
A year is longer than it feels while you are inside it.
We started this because one of us found a birthday card they had written to themselves at nineteen, and the thing that stopped them was not the advice. It was how certain that person had been that nothing would ever change.
It had. All of it. Quietly, without anyone announcing it, in the ordinary way things do.
