Cordo is an iPhone app that helps build confidence from your own evidence. Deposit what you did. Each deposit turns your focus to what you did, not what went wrong. Over time it all adds up.
The problem
That’s how memory is wired. But how capable you feel shouldn’t depend on what you happen to remember.
Deposit what you did
Answer one or all of them, in your own words, whenever it suits you.
That’s a deposit. Each deposit is a practice in noticing your accomplishments.

Why it works
Cordo is a daily practice for building confidence.
It’s shaped around research and proven concepts.
We tend to hold onto what goes wrong and let the good slide off — one of the better-documented habits of memory. Banking what you did on purpose is how you keep it: the practice does deliberately what memory won't do for free.
In the research on self-efficacy, the strongest source of belief in your own ability is having done the thing before. Every deposit is a piece of that record, in your own words, that you can point to.
Memory research finds that bringing something back to mind makes it easier to reach for next time. Most of those studies are about learning facts, but the mechanism is the same: revisiting your evidence is practice at finding it when you need it.
Athletes review what actually happened in the game rather than telling themselves it went well. Confidence you can trust is the kind you can back up, and a record of what you did is something you can look at.
