How do you write a letter to your future self?

Pick a date you can picture — one year is the usual choice. Write to a specific person rather than an abstraction: where they are living, what their Tuesday looks like, what they are no longer carrying. Say what is true now without editing it, name what you are afraid will still be true, ask five or six real questions, and end with one sentence you would want to hear on a bad morning. Then send it somewhere it will actually arrive.

What should I write in a letter to my future self?

Concrete detail beats sentiment. Where you live, what you do first in the morning, what the money situation is, who you are close to, what you are avoiding. Those specifics are what makes the letter worth opening later — a year from now you will have forgotten them entirely, and that forgetting is the point of the exercise.

How long should the letter be?

One page, or about twenty minutes of writing. Long letters get written in a burst of feeling and are hard to reread. A single page of specifics is more useful than four pages of encouragement.

Where can I send a letter to my future self?

Free services such as FutureMe email a letter back on a date you choose. A calendar entry a year out with the text pasted into it works just as well. Offline: seal it in an envelope, write the date across the flap and put it somewhere you will not tidy away — the back of a drawer, inside a book you own but do not read.

Does writing to your future self actually do anything?

There is real research behind the idea, though not the version usually sold. Hershfield and colleagues found in 2011 that people who interacted with an age-progressed rendering of themselves subsequently allocated more money to retirement than those who did not. The finding is about future self-continuity: the more your future self feels like a person rather than a stranger, the more willing you are to act in their interest. A letter is a low-tech way of making that person specific.

What is the difference between a letter to your future self and a vision board?

A letter is written once and opened once, which makes it an event. A vision board is meant to be seen daily, which makes it a habit — and which is why it goes stale faster. Letters tend to be more honest, because nobody arranges a letter to look good on a wall.

How to write a letter to your future self

A method that takes twenty minutes, twenty prompts if you get stuck, somewhere to send it so it actually arrives — and the version of this exercise where the letter comes the other way.

Why the exercise does anything

Most people write to their future self at a turning point — the last day of a job, the first week in a new city, the birthday with a zero in it. The instinct is sound, and there is research underneath it that is more specific than the usual encouragement.

In 2011 Hal Hershfield and colleagues showed people a realistic, age-progressed rendering of their own face and then asked them to make financial decisions. Those who had met the older version of themselves put noticeably more of their money aside for retirement. The mechanism they describe is future self-continuity: for most of us the person we will be in twenty years is filed somewhere near a stranger, and we treat that stranger's interests accordingly. Make them specific enough to recognise, and the arithmetic changes.

A letter is a low-tech version of the same move. It is not a wish and it does not summon anything. It makes a stranger into somebody you have met.

Three decisions before you write

When it arrives. One year is the standard, and it is standard for a good reason: near enough that you can picture the person, far enough that the letter will genuinely surprise you. Five and ten years are for turning points. Under six months is a note, not a letter.

Who you are writing to. “Future me” is too vague to write to. Write to the person who wakes up on a specific morning in a specific room. If you cannot picture the room, that is the first thing worth working out.

Where it goes. Decide this before writing, not after — the letters that get lost are the ones written without a destination. Options further down.

How to write it

Date it, and address it to that morning. “It is the 29th of July next year and you are reading this in…” Starting inside a scene keeps the whole letter concrete.
Say what is true now, without editing. The money, the job, the flat, who you are close to, what you are avoiding. Unflattering detail is the part you will be most glad of. You will have forgotten all of it within the year, which is exactly what makes the letter worth opening.
Name what you want, in ordinary terms. Not a title or a number — a Tuesday. What is the first hour like? What is on the table? Whose calls do you answer?
Name what is in the way, honestly. This is the step most letters skip and the one the research keeps pointing at: a picture of the good ending, held next to nothing, tends to cost you energy rather than give it. Write the obstacle down next to the want.
Ask five or six real questions. Questions are what make a letter a letter and not a diary entry. Prompts below.
End with one sentence for a bad morning. Whatever you would want to hear if the year has not gone well. Not a slogan — something you would actually say to someone you love.

One page. Twenty minutes. Long letters are written in a burst of feeling and are hard to reread; a page of specifics beats four pages of encouragement.

Twenty questions for your future self

Take five or six, not all of them. The good ones are the ones you cannot answer quickly.

What does your first hour look like now?
Which room are you reading this in, and did you choose it?
What did you finally stop apologising for?
Who did you stop waiting for?
What did you spend money on that turned out to be worth it?
What are you no longer carrying?
What does an ordinary Tuesday look like?
Whose call do you answer straight away now?
What did you say no to, and was it hard?
What is on the table when you eat?
What did you start learning that you were embarrassed to be bad at?
What became boring, in the good way?
What still frightens you?
What did this year cost, honestly?
Who helped — and did you tell them?
What did you keep from the person writing this?
What did I get wrong about what I wanted?
What is the first thing you do when you get home?
What are you better at than I am?
If you could send one sentence back to me, what would it be?

Where to send it

By email, scheduled. Free services such as FutureMe hold a letter and send it back on a chosen date; several phone apps do the same as a private time capsule. Convenient, and dependent on the service still existing on the day — and on you still using that email address.

In your own calendar. An all-day entry a year out with the letter pasted into the notes field. Unglamorous, free, and it will not disappear when a company does.

On paper. Seal it, write the date across the flap, and put it somewhere you will not tidy away: the back of a drawer, inside a book you own but do not read, taped behind a picture frame. Paper letters are the ones people actually cry over. They are also the ones people lose.

Four things to avoid

Instructions. A list of orders to a person who will know more than you do reads badly a year later. Ask instead.
Only the good ending. A letter that describes the win and nothing else is the fantasy the research warns about. Put the obstacle in.
Grand language. The lines that survive a year are the small ones — the key turning on the first try, not the ceremony.
No destination. A letter in a notes app you will never reopen has not been sent. Decide where it goes before you write it.

The version where the letter comes the other way

Every app in this category runs in the same direction: you write, time passes, the letter arrives. It is a good exercise and it happens once.

Faye runs it backwards, every morning. You describe the life you are moving toward once, in your own words — the room, the street, the work, the people. Then each night Faye writes one short scene out of that description: a specific, present-tense moment from that life, ordinary detail, your own words folded back in. In the morning she reads it aloud to you, about four minutes, before the day starts.

So instead of you writing forward to a stranger, the life you said you wanted keeps writing back — in the second person, out loud, on a Tuesday. That is the same lever Hershfield's work points at, pulled daily rather than once a year: the future self stops being an abstraction because you keep hearing about their morning.

It claims nothing about how the world works and promises no outcome. What it does is narrow: it keeps a specific picture of the life you want in front of you, in your own language, before the day starts. The honest comparison is mental rehearsal — what athletes do before a race.

If you want to read further

Hal Hershfield's Your Future Self (2023) is the book-length version of the continuity research above, written by the person who ran most of it. Benjamin Hardy's Be Your Future Self Now (2022) covers similar ground from a self-development angle and is the title most people mean when they search for a future self book. Gabriele Oettingen's Rethinking Positive Thinking is the one to read if the obstacle half of this page is the part you want more of.

Questions people ask

How do you write a letter to your future self?: Pick a date you can picture, write to a specific person on a specific morning, say what is true now without editing, name the obstacle as well as the want, ask five or six real questions, and end with one sentence for a bad day. Then send it somewhere it will arrive.
What should I write about?: Concrete detail rather than sentiment: where you live, the first hour of the day, the money, who you are close to, what you are avoiding. You will have forgotten all of it in a year, which is what makes it worth opening.
How long should it be?: One page, about twenty minutes. Long letters are hard to reread.
Where do I send it?: A scheduled-email service such as FutureMe, a calendar entry a year out, or a sealed envelope somewhere you will not tidy away.
Does it actually do anything?: The useful version of the claim: making your future self specific makes you more willing to act in their interest — that is what Hershfield's saving experiments found. A letter is a cheap way of making them specific. It is not a mechanism for causing events.
Letter or vision board?: A letter is an event, opened once, and tends to be more honest. A vision board is a habit, seen daily, and goes stale faster. They are not competing — the letter is where the honesty goes, the board is what stays in the room.
