A time capsule letter is a list of the ordinary: the bus, the coffee, the song, the price of bread. Here is what to put in it.
What a personal time capsule is for
A time capsule is a box of ordinary things sealed for a later reader. Most famous ones are large public projects, but a personal time capsule is smaller and more useful. You are not trying to impress anyone. You are trying to leave a clear picture of your life as it is today, for the person who opens the letter.
The common mistake is to write only the highlights. A capsule of promotions and holidays reads like a brochure. A capsule of the bus route, the coffee order and the song on repeat shows what a normal week felt like. The second version is worth far more.
You can write the whole list as one letter on Letter to Future Self. The form takes up to 30,000 characters, so a long list fits. No email arrives when you write it, so copy the text somewhere you will find it before you finish.
The small details people forget
Ask yourself what you would never remember in 10 years. The answers are rarely the big events. They are the small things you stop noticing because they happen every day.
A few details often slip away: the app you open first each morning, the song you have played all month, the bus stop where you get off, and the friend you call on Sundays. Write each one as a short line.
These details feel dull now. A year from now they will be the things that bring the day back. A line like “I took the 14 bus and got a coffee from the cafe by the station” can do more for a reader than a paragraph about how you felt.
People belong in the record too. A 2006 paper by Wildschut and colleagues in the Journal of Personality and Social Psychology found that nostalgic memories usually feature the self with close others or at big moments, and that they hold more positive feeling than negative. It studied nostalgia, not time capsules, but it is a good reason to put the friend you call on Sundays on the list.
Things to record today
Go through this short working list in order. Write one or two lines for each item, and add a small amount of detail to each line. “Coffee” is vague. “Flat white from the kiosk by the station, no sugar” is a picture.
- Where you live, and the room you spend the most time in.
- The routine of an ordinary weekday, from waking up to going to sleep.
- Two or three things you buy often, and where you buy them.
- The apps, shops and services you use now, which will probably change.
- The people you see or speak to in a typical week.
- What a loaf of bread or a bus ticket costs at the moment.
Item 4 matters most for the reader. Name the apps and shops even if you think they will be gone by then. A future reader will be glad to know what was in use, and they will not expect you to be right about what lasts.
Keep the list honest. You do not need to make your life sound interesting. A quiet weekday is exactly the kind of day that tells a reader what the world was like for you.
Write about the world as you see it
A letter from today will be read in a world that has moved on. You can help the reader by describing the world as you see it, with dates. Keep this part short. Choose one or two things in the news this month that worried or interested you, and write the date beside each one.
Mark these lines clearly as context. For example: “This is what the news looked like to me on this date. I may have misjudged how much it mattered.”
Describe what happened and how it felt to you. Do not argue about who was to blame, and save your guesses about what happens next for a separate predictions letter. A future reader will know the outcome better than you do, and that is the point.
A sample time-capsule letter
Here is a short sample. It describes one ordinary Thursday, the kind of day nobody would think to save, and it names a price and two apps.
Dear future me,
It is a Thursday in October, and I am writing this on the bus, which is late again. The coffee order is still an oat latte, [price] now, and the barista knows my name without asking. I check the weather app before I am out of bed and the bus app before I am out of the door. My neighbor's brown terrier barked at me from the gate, as if the street were his to guard. One thing on my mind this week: the rent letter with the new figure. The song I cannot stop playing is “[song title].”
[your name]
The letter has no speeches and no goals. It shows one Thursday, with details the reader can picture and a price to wince at, and it gives the reader a reason to smile at the dog.
Seal it, store it, and leave it alone
Old capsules are often forgotten. For your letter, the important choice is the date. Letter to Future Self offers presets from one day to three years, and a “choose date” option for anything up to 20 years ahead. Pick a date far enough away that the list will feel different when it arrives.
There is no way to edit or cancel a letter on the site after you send it. Read it through once more before you finish, and make sure the list says what you mean. Put the date in your calendar.
Keep your copy in a folder you can find years from now. Then leave the letter alone until the day it arrives. Most of the value of a time capsule is the surprise of opening it.
Write it now
Pick an ordinary day from this week and write 10 small details, one line each, including one price and one app. Add one thing you would be sad to lose and one thing you expect will have changed. Then choose a date five years or more away, and send it.
