Intentions are cheap. Evidence isn't.

Identity

Who you're becoming

An athlete. A son who calls. Someone who kept their word to themselves. Behaviour holds when it's a vote for a person, not a number.

Goals

What that looks like

Say it out loud, however it comes out. FIREBIRD sorts a ramble into goals you'd actually recognise as yours.

Challenges

What you'll actually do

Specific enough to argue about, on a real schedule. Text one person or ten and they're in it with you.

Receipts

Proof you did it

Dated, numbered, countersigned by whoever was watching. Something to keep, and something to send.

When the story stops fitting, burn it down and start again.

The FIREBIRD flow is four steps you can run any time things drift — and a reminder every Sunday if you want one. Whatever you write is kept.

ReflectSay what's going on.
RemoveName what's in the way.
RevealFind the one thing that counts.
RiseDo it. Keep the receipt.

A checkmark disappears. A receipt is a thing you keep.

Habit apps give you a grid of squares that means nothing to anyone else. FIREBIRD gives you something worth sending: the date, the action, what actually happened, the streak, and the name of the person it belongs to.
