Labels
Labels are shortcuts, and efficiency can be good -- sometimes. More often, labels come with preconceptions that are never tested, that deny any variance, and put unnecessary walls up around people.
We’re all busy. We want the shortcut. Acknowledge that its there. Use it if necessary. But never let it become the default, lest we walk blindly - never testing our preconceptions, flattening our vision of the world, and never walking through walls that weren't meant to be there in the first place.
