A pocket-size check-in card for the moments when something feels off.
When something feels wrong and you don't know why, run the HALT check. Hungry. Angry. Lonely. Tired. Most of the time it's one of those, and most of the time naming it shrinks it.
This is the printable version. One page, front and back. Print it, fold it in half, keep it in your wallet or your car. Pull it out when you need it. $3 because nobody should be priced out of a tool this small.
