If you’ve ever promised yourself you’d start something “next month” and then… didn’t, it’s not just a willpower problem. It’s a perception problem. Your brain quite literally treats your future self like a different person — and that disconnect is exactly why so many good intentions fizzle.
The good news? There’s a simple, human intervention that pulls your future self back into focus: a letter.
The Research: Your Future Self Is a Stranger (Literally)
Hal Hershfield, a behavioral scientist at UCLA, has spent years studying what he calls future self-continuity — how connected you feel to the person you’ll be in 10, 20, or 30 years. What he’s found is both surprising and deeply practical:
- Most people struggle to feel continuity with their future selves. In fMRI studies, when participants think about their future self, brain activity looks more like it does when they think about a stranger than when they think about themselves today.
- People who feel more connected to their future self make better long-term decisions. They save more money, follow through on goals, and take better care of their health.
- Future self-continuity isn’t fixed. It can be increased with small, concrete interventions — things that make the future feel more real, personal, and emotionally close.
One study Hershfield co-authored puts the effect on exactly this exercise. In “Vividness of the Future Self Predicts Delinquency” (Van Gelder, Hershfield & Nordgren, Psychological Science, 2013), participants who wrote a letter to their future self were less inclined toward impulsive, shortsighted choices than a control group who didn’t. The letter itself was the intervention.
In other words, your future self isn’t some abstract “someday you.” They’re a real person with bills, hopes, tired mornings, and a heart that beats just like yours. The problem is that your brain doesn’t always act like it knows that.
This is where letters come in.
Letters Turn “Future Me” Into a Real Person
Think about the last time someone wrote you a letter that mattered. Maybe it was a note from a friend, a card from a parent, or a college acceptance letter. You didn’t just read it — you felt it. Letters make things feel personal, tangible, and worth holding onto.
A letter to your future self does the same thing in reverse: it makes your future feel personal, tangible, and worth showing up for.
When you write a letter to your future self:
- You give your future self a name, a voice, and a face. You’re not sending something into the void; you’re talking to a specific person: you, on a specific date.
- You make your future concrete. Instead of “I’ll be healthier someday,” it’s “I hope you’re finally walking without knee pain. I started that routine we both keep saying we would.”
- You create emotional stakes. A sealed envelope is a promise. It says: “I spent time on you. I believed in you. I’m counting on you.”
That’s the magic Hershfield’s research points to: when the future feels like a real person you care about, you act differently today. (It’s also why the waiting itself does real work — a letter you can’t open for a year behaves differently in your head than a note you could read this afternoon.)
What Kind of Letter Works Best?
You don’t need perfect prose. You don’t need to be a “writer.” You just need to be specific and honest. The most effective future-self letters tend to:
- Speak directly to future you (“Hey you, it’s 2026-me…”)
- Include details only you would know (inside jokes, specific struggles, small wins)
- Mix hope with realism (“I know you’re tired, but I also know you made it this far”)
- End with a question or invitation (“What are you proud of right now?” “What’s one small thing you’ll do for us next week?”)
If you want a more structured walk-through of the blank page, our guide to writing a letter to your future self and the seven-section letter template both go deeper. And there’s a growing body of research on why this helps your head as much as your habits — we rounded it up in the piece on expressive writing and wellbeing.
A small nudge on the writing itself: doing this by hand tends to slow you down in a good way. If you don’t already have a pen you love, a Lamy Safari fountain pen is the one I hand people most often, and a vintage-style letter paper and envelope set makes the whole thing feel like it matters more. Neither is required — honesty is the only ingredient that is.
How Hold My Letter Helps You “Meet” Your Future Self
Hold My Letter holds your letter and delivers it on a date you choose — months or up to two years from now. It’s not a journaling app that pings you with a push notification. It’s a physical, sealed letter that arrives in your mailbox, in the real world, as if someone who knows you deeply sent it to you.
Because they did: you.
Here’s how it works:
- Write your letter. Speak to your future self as if they’re already real. Tell them what you’re going through, what you hope for them, what you want them to remember. Don’t worry about grammar or style. Nobody is grading this. You can type it online ($9) or handwrite it and mail it to us ($19).
- Choose your delivery date. Six months from now. One year. Two. A date that matters: a birthday, a milestone, a “check-in” point.
- We hold it, then mail it. Your letter is stored securely until your chosen date, then printed on cream stationery (or kept in your own handwriting) and mailed to you the old-fashioned way. No emails. No reminders. Just you, your name on an envelope, and a moment that suddenly feels much more real.
People use Hold My Letter for all kinds of check-ins:
- New Year letters to future-self
- Post-surgery or recovery encouragement notes
- Letters to open after breakups, job changes, or big moves
- “I’m starting something new — future me, how’d it go?” check-ins
All of them are variations on the same idea: making your future self someone you actually care about.
A Simple Way to Start (No Pressure)
If you’re skeptical, that’s fine. Try something small:
- Set a date 6–12 months out.
- Write one page.
- Tell future you three things: what’s hard right now, what you’re hoping changes, and one thing you want them to remember about you.
Then send it and forget about it. When it arrives, you’ll get to see what happens when your brain finally treats your future self like someone real.
Frequently Asked Questions
Isn’t this just journaling?
Not quite. Journaling is mostly for present-you. A letter to your future self is directed, personal, and time-delayed — written for future-you specifically. The research on future self-continuity suggests that the more concrete and specific the future feels, the more effective the intervention. A sealed letter scheduled to arrive on a real date makes the future feel much more concrete than a private note in an app.
What if I’m bad at writing?
Nobody is grading this. The goal isn’t a perfect essay; it’s a real conversation with a person you care about — you. If you can text a friend or leave a voice note, you can write this.
How long should my letter be?
As long as it needs to be — one page is usually enough. Focus on honesty and detail, not length.
Can I write more than one letter?
Yes. Many people create a series: one for six months out, one for a year, one for two years. Each becomes a checkpoint with your future self. Our delivery window runs from one month to two years out.
Is this only for big life changes?
No. Some of the most powerful letters are about small, ordinary things: a rough season at work, a fitness goal, learning to be kinder to yourself. The more normal it feels, the more your future self will recognize it as real life.
You don’t need to wait for a crisis or a milestone to start treating your future self like someone who matters. You can start today, with a simple letter.
Hershfield’s research shows that people who feel connected to their future selves save more, follow through more, and take better care of themselves. Letters are one of the easiest, most human ways to create that connection.
If you’re ready to try it, write your letter, pick a delivery date, and write like you’re talking to someone you love.
Because you are.
