One unexpected thing to do every month.

A card arrives in your mailbox. You don’t know what’s on it. That’s the point.

$12.99/month or $99/year · No app. Just mail.

One envelope. One card. One thing to do.

Your mailbox has plans for you.

Once a month, an envelope turns up with your name on it. Inside is one printed card with one specific, slightly unexpected thing to do — and how long you’ve got to do it.

The one below is an example. Every subscriber gets something different — including you.

How to read a card

  1. Card 024. Every card has a number. Back to the card
  2. The Detour. A title you can say out loud: “I got The Detour.” Back to the card
  3. The thing. What you actually have to do — specific enough that you can’t wriggle out of it. Back to the card
  4. Wildness 03/05. How far outside your routine it goes. Back to the card
    1. Wildness 1: barely outside your routine
    2. Wildness 2: slightly unusual
    3. Wildness 3: you’ll probably remember this (this card)
    4. Wildness 4: okay, this is getting weird
    5. Wildness 5: absolutely ridiculous
  5. You have 7 days. A deadline, so it doesn’t live on the fridge forever. Nobody checks. You’ll know. Back to the card

You don’t pick the card. That’s the whole idea.

Every month, one card shows up with one unexpected thing to do — something to knock you slightly off your usual route.

Which one? You’ll find out at the mailbox.

It might have you…

  • Go somewhere you’ve never been
  • Talk to someone you’d normally walk past
  • Try something slightly strange
  • Call someone you’ve lost touch with
  • Do something generous for no reason
  • Learn one thing you didn’t need to know
  • Take a ridiculous detour
  • Do the thing you’d normally talk yourself out of

Everything is getting better at predicting you.

We thought you could use a little randomness.

Nothing against algorithms. Your map really is great at the fastest way home. It’s just that nobody’s best story starts with “so I took the fastest route.”

Once a month, this happens.

  1. A card arrives.

    In your actual mailbox, somewhere between the bills and the takeout menus.

  2. You open it.

    You don’t know what’s inside until you do.

  3. You do the thing.

    Whenever you decide to take it on. The card says how long you’ve got.

  4. Something happens.

    Maybe you laugh. Maybe you meet someone. Maybe you find a place you’ll go back to. Maybe you hear a voice you haven’t heard in years. Maybe you just get a good story.

Then next month, a different card. And one more story to tell.

Not a better you. A better Tuesday.

This isn’t self-improvement. It’s life, improved by accident.

It isn’t a productivity system, a wellness program, a self-help course, a habit tracker, an app, or another feed. It’s an excuse to take the long way, an errand with a plot twist, a slightly ridiculous dare, a one-off, a piece of paper, and a story you’ll tell later.

No progress bars. No notifications. Nobody’s grading you. Do the card, skip the card, you do you.

Give someone a year of stories.

Twelve envelopes they won’t see coming. Neither will you.

01 to 12. One a month. None of them predictable.

Good for:

  • To:someone who already owns everything
  • To:a friend who just moved to a new city
  • To:the couple with an anniversary coming up
  • To:your mom, who “doesn’t need anything”
  • To:your dad, who has enough mugs
  • To:the friend whose birthday you always remember two days late
  • To:whoever’s hardest to buy for at Christmas

Fair questions.

What actually comes in the mail?

One physical card with one unexpected thing to do on it. In an envelope, in your mailbox, once a month.

Can I choose what I get?

No. That’s the point.

Will everyone get the same card?

Not necessarily. Cards are intentionally varied.

Is this a greeting-card subscription?

No. The card isn’t a message. It’s an invitation to do something.

What if I don’t want to do the card?

You don’t have to. But we recommend giving it a chance. The ones you want to skip might make the best stories.

Can I give it as a gift?
Do I need an app?

No. The card works by itself. It’s paper.

Less
algorithm.
More life.

One card. One unexpected thing. One small interruption to your normal life.
