A Letter From Your Future Self: How to Write One, With Examples
A letter from your future self flips the usual exercise. Instead of writing to the person you will be, you write as them, looking back at today. It takes about twenty minutes and needs nothing but a pen. Done well, it gives you a clear picture of where you are heading and one small thing to do this week. This guide gives you a structure, two complete examples and a way to use the letter once you put the pen down.
What is a letter from your future self?
It's a short letter written in the voice of you at a set point ahead, often 90 days or a year. Your future self describes what their days look like, what changed, and what the present you did that mattered. It's an exercise in imagination, not a prediction. Its job is to make a distant goal feel concrete enough to act on today.
It's different from a letter to your future self, which records who you are now so you can read it later. Both are useful. This one points forward.
Why write as your future self instead of to them?
Researchers who study future self-continuity have found that people who feel more connected to their future selves tend to make choices that favor the long term, such as saving more (Hershfield, 2011). Writing in that person's voice is one simple way to build the connection.
A related exercise, the best possible self, asks people to write about a future in which things have gone well. A 2019 review of 29 studies found small to moderate gains in optimism and wellbeing compared with control exercises (Carrillo et al., 2019). That's a modest effect, not a transformation, and it comes from doing the exercise, not from believing the letter will come true.
How do you write a letter from your future self?
Write quickly and don't edit. Aim for 200 to 400 words.
- Pick a date. Ninety days is a good default: near enough to plan for, far enough for a routine to change. Write the date at the top.
- Start with an ordinary morning. Describe one normal day in that future. Where are you, what do you do first, how do you feel? Ordinary details are more useful than big milestones.
- Name what changed. Give two or three specific differences: I run three mornings a week, not I'm healthier.
- Look back at today. Have your future self describe the present you honestly, including what felt hard.
- Credit the small choices. Which actions, repeated, got you there? This is the part you will use.
- End with one request. Close with one small thing your future self asks you to do this week.
Example: a letter from 90 days ahead
February 3
Dear me in November,
It's a Tuesday and I'm writing this before work, at the kitchen table, which is now where I write. Three mornings a week I'm out the door at 6:40 for a 25-minute run. I won't pretend I love every one, but I haven't skipped two in a row since December.
I remember how you felt in November. Tired, behind, and sure that starting in January was the only way. You were also scrolling until midnight and then wondering why mornings were impossible.
What changed wasn't motivation. You put your phone on the charger in the hallway at 10:30. You laid out your shoes the night before. On the mornings you didn't run, you walked around the block so the habit stayed alive. That's it. Those three things, repeated, did most of the work.
The race in March doesn't feel scary anymore. It feels like the next thing.
This week, I only need one thing from you: move the charger to the hallway tonight.
Me, in February
Example: a short letter from one year ahead
Dear me,
A year from now, the credit card is paid off. Not because of one big month, but because every Sunday you checked the balance for five minutes instead of avoiding it. You also stopped buying lunch on Mondays and Thursdays. Small, boring, effective.
This week: set a Sunday reminder and look at the number once.
Me, next November
What should you do once the letter is written?
- Pull out the request. Copy the final ask onto a sticky note or into your habit tracker. A letter that changes nothing this week was nice writing and nothing more.
- Turn the small choices into habits. Each action from step 5 can become a daily or weekly practice. Start with one, maybe two. Our guide on how many habits to start at once explains why.
- Reread it on Sundays. A quick reread before your weekly review keeps the picture fresh.
- Write back. If something in the letter feels unrealistic, reply to it. Disagreeing with your future self is often where the useful plan appears.
- Update it at day 30. Your picture of the future will shift. People consistently underestimate how much they will change (Quoidbach, Gilbert and Wilson, 2013), so revising is part of the exercise.
What if writing as your future self feels fake?
That's common at first. A few things help:
- Write about one hour of one day, not your whole life.
- Use I'm learning to instead of I am if the bigger claim feels untrue. Our guide to identity-based habits covers this.
- Let your future self admit things are still imperfect. Believable beats impressive.
- If the letter brings up something painful, set it aside. This is a reflection exercise, not therapy, and it's fine to talk to someone you trust instead.
Can an app write letters from your future self?
Yes. In the Future Self app, you set goals in two or three areas of life for the next 90 days and check off small daily habits. Each day, an AI-generated letter written from the perspective of your future self reflects the habits you completed, and on Sundays a longer letter imagines life with your goals reached. You can write back and get a reply in the same voice.
The letters are generated by AI from your goals and activity. They're prompts for reflection, not predictions or professional advice. Writing your own letter first gives the app's letters something real to build on.
Frequently asked questions
How long should a letter from my future self be?
200 to 400 words is enough. Length matters less than one specific detail about an ordinary day and one clear request for this week.
How far ahead should I write from?
Ninety days suits a routine or habit. A year or more works for direction in work, money or relationships. Try both and compare.
Is this the same as manifesting?
No. The letter doesn't make anything happen. It clarifies what you want and points to an action you can take, which you then test in real life.
How often should I write one?
Once at the start of a 90-day stretch, then a fresh one about every 30 days or when your goals change. Rereading weekly is more useful than writing often.
What's the difference between a letter to and a letter from my future self?
A letter to your future self records the present for later reading. A letter from your future self imagines the future to guide what you do now.
