Letter From Your Future Self: How to Write One That Helps

A short method, three templates you can copy, and a fair look at what the research suggests.

A letter from your future self is a note written as the person you will be after you have reached a goal, addressed to the person you are today. To write one, pick a date and describe your life there in the past tense. Say what you did that mattered, name the obstacle you got past, and end with one specific instruction for today.

Why write to your future self

Most of us treat our future self like a stranger. It is easy to ask a stranger to do the hard work. Psychologists call the sense of connection to the person you will become future self-continuity, and some studies suggest strengthening it may change what people do now.

The clearest example for letters is a study by Alexander Rutchick, Michael Slepian, Hal Hershfield and colleagues, published in the Journal of Experimental Psychology: Applied in 2018. Undergraduates were randomly asked to write a letter to themselves either 20 years or three months in the future. Those who wrote to the distant self exercised more over the following days, about 3.66 extra minutes a day on average (source). The sample was 535 students. The authors called the effect modest, and exercise was self-reported in daily diaries over 2 to 10 days. That study used letters written to a future self. We know of no study of letters written from the future self.

A 2025 systematic review of future self-continuity interventions, covering 14 articles and 23 studies, called them promising for behavior change, with effects ranging from negligible to very large. It also noted that most studies used young adults from universities or online panels, and only one included people who said they wanted to change (source). So the honest summary is: a reasonable habit with early, encouraging evidence.

Six steps to write the letter

Choose your date. One year out works for most goals. For a big goal such as a book or a business, try three years. Write the date at the top.
Open in the done state. Start with the result in the past tense. "Dear me, it is 1 June. The book has been out for two months, and I am writing this between reader emails."
Add three ordinary details. Where you sit, what you had for breakfast, who you spoke to. Ordinary details make the letter feel like a place and not a poster.
Tell the story of the hard part. Name the obstacle you faced and the small thing you did about it. "Around month four I kept editing the same chapter. What worked was typing the next sentence badly."
Give today's self one instruction. Specific and small. "Tonight, write for 45 minutes. Do not reread. Log what you wrote."
Sign it and date the reply. Put a reminder to reread it in a month. Then write a two-line reply as today's you: what you did.

Three templates to copy

Template 1: the finish-line letter

Dear [your name],
It is [date]. [Goal, in the past tense]. Here is what an ordinary day looks like now: [three details].
The thing that mattered most was [one action you repeated]. The hardest stretch was [obstacle]. What got me through was [small if-then plan].
Today, please [one 45-minute action]. That is all.
[Your name], one year from now

Template 2: the letter for a hard day

Dear [your name],
You are probably about to quit or skip today. I remember that feeling. Here is what I want you to know: [one true thing about your progress, drawn from your done list].
You do not have to do the whole thing. Do [the 10-minute version]. Then stop.
See you on the other side.

Template 3: the decision letter

Dear [your name],
You are deciding whether to [decision]. Looking back from [date], here is what I wish you had weighed: [two or three points]. Here is what turned out not to matter: [one point].
Whatever you choose, do [small next step] first.

A short example

"Dear Sam, it is 14 March next year. I ran the 10k on Sunday and finished feeling strong. The mornings are quieter now. The hardest part was November, when it was dark and cold. What worked was putting my running clothes next to my bed the night before. Today, lay out your clothes for Thursday and run for 25 minutes. That is the whole job. Sam."

Notice what is not in it: promises, predictions of luck, or claims about the universe. It describes a plausible future and a real next step.

What to avoid

Fortune telling. You cannot know how things will go. Write a plausible future, not a certain one.
All highlights. A letter that skips the hard part reads like an ad. Include the obstacle, and how you handled it.
No instruction. If the letter ends without a task, it is a daydream. Oettingen and Mayer (2002) found that positive fantasies about the future predicted less effort in several groups (source). The instruction, and the obstacle plan, are what keep a letter from being only that.
A scolding tone. A letter that lectures is easy to ignore. Write as someone who has been where you are and is on your side, because you will be.
Writing it once. Reread it monthly. Update it when your goal changes, and keep the old versions so you can see how your thinking moved.

When to write one

Letters earn their keep at turning points. Consider writing one:

At the start of a new goal, so the end point is fixed before the work begins.
At a stall, when the goal has slid for two or three weeks and you need a reason to restart.
Before a decision, to look at the choice from a calmer place.
At a birthday or the new year, as a yearly ritual you can reread next time.

Keep each letter short. Half a page is enough, and about 10 minutes. A long letter is harder to reread, and rereading is where much of the value is.

A useful trick is to write in the voice of a friend who happens to be you. Skip the pep talk. A calm, specific note ("here is what worked, here is what to do tonight") is easier to believe than a cheerleading one.

Handwritten, typed or spoken

Handwriting slows you down and can feel more personal. Typing is faster and easier to update. Reading a letter aloud, or hearing it, can make it harder to skim. There is no research we know of that ranks these formats for goal follow-through, so choose the one you will actually reread.

Start From Done builds a letter from your future self from a template on your device, using your plan. It is not written by AI. Free users can read it, and Pro users can record it in their own voice. The letter is a companion to the plan, not a replacement for it.

Where the letter fits in the loop

A letter works best as one step in a routine. Write it after you have set a goal and a path back, then reread it when your motivation dips. For prompts to write from, see future self journal prompts. To turn the letter into a plan, use reverse goal setting. For the full loop, read Reverse Journaling, and log what you did on a done list.

Questions

How do I write a letter from my future self?

Pick a date, open in the done state and the past tense, and add ordinary details. Describe how you got past the hard part, and end with one specific instruction for today.

How far in the future should the letter be?

The 2018 study compared letters to a self 20 years ahead with letters to a self 3 months ahead. It did not test one-year letters. One year is a practical starting point for most goals, and three years suits large ones.

Does writing a letter to your future self work?

Early studies suggest a small effect on behavior, such as exercise, and a 2025 review called future self-continuity interventions promising. The evidence is limited and mostly from young adult samples.

What should I include in the letter?

The done state, three ordinary details, the obstacle and what got you past it, and one small instruction for today.

Can Start From Done write the letter for me?

Yes. The app assembles a letter from a template on your device, using your plan. It is not written by AI. Free users can read it. Pro users can record it in their own voice.
