Affinity sorting
What it is
Affinity sorting is basically the sorting of a huge amount of information, usually split on sticky notes (digital or physical). The sorting is done without thinking of the categories at first, but the categories slowly reveal themselves as you sort each sticky note after the other.
It's a great way to go from overwhelming information to clarity. And it works even to get you out of a panic moment when your wife tells you: "I'm pregnant". In fact I've used that method with my wife to sort all the thoughts, fears, tasks we had in our minds into a clear plan. And yes this helped us remember that health insurance is an important thing, so thanks affinity sorting for that!
