Keeping a journal works. Writing a letter to someone works. But writing to your future self has something neither of those has: it forces you to believe that self will exist.
When you go through a hard time, one of the first things to break is your ability to imagine yourself doing better. It is not just that you are sad: the film in your head switches off, the one that lets you picture yourself in six months, in a year…
Writing to your future self forces that picture back on. Even if you do not want it to. Because when you write “Dear me, one year from now…” you are stating, without realising it, that there will be a you one year from now.
That is why the future is a different kind of listener. It does not judge you. It does not correct you. It only reads you when the time comes. And in the meantime, writing to that person who does not exist yet helps you build them.
Writing by hand is something else. It is slower, and that is exactly why it works differently: your hand lags behind your thoughts and forces you to know what you want to say before you say it.
And your handwriting tells things words do not. Whether you wrote in a hurry. Whether you pressed hard on the pen. What you crossed out and decided to leave crossed out. Years from now, all of that can be read too.
You write the letter. You sign it. And you close it by folding the corners marked with the dotted line. If you like, add some tape, a sticker or a little wax.
From then on, to read it early you would have to break something with your own hands.
In the journal you will find a log to keep track of all your letters: you note when you wrote each one and when you will open it, and tick the box on the day you read it. It is your pact with yourself: none before its date.
That small obstacle is the whole idea: it turns an intention into a gesture. And gestures stand the test of time much better than good intentions.
The letter stays with you, sealed, wherever you decide to keep it. But each one has its own code: you register it here in a minute and we remind you on the day it is time to open it.
Paper keeps it safe. We take care of remembering.
Letters for you to write, with just enough to get going on the days when you do not know where to start.
And five letters saved for specific moments in your life: the day things go well, a day when everything feels heavy, the day you need someone to remind you who you were.
This is the end-of-year one: the one that turns December 31 into a conversation.
Five minutes a month: one word to describe it, how you have been, something that happened that you want to remember, a sentence for your future self.
So that everyday life is not lost, because it is the first thing we forget.
Small promises, the size you can actually keep. The kind of sentence you only dare to put on paper.
The rest is better when you open it.
Yes. In fact, the journal was born from this project: a free platform where anyone can write a letter to the future and receive it on the day they choose. And it will stay here, free, for as long as you want. The book is not here to replace it: it is here to go alongside it.
Here
To write from wherever you are. On your phone, in five minutes, on the day you remember.
Write a letter nowIn the book
To sit down, switch off your phone and write by hand with nothing interrupting you.
And there are two things a screen cannot do: a book can be given as a gift, and it stays on a shelf, in sight, reminding you that you have a letter waiting.
The journal is finished and the Spanish edition comes out in October; the English edition is next. If you like, we will let you know the day you can hold it in your hands.
