Attention is built to hunt for what's wrong — the broken thing, the missing thing, the threat. It's kept us alive, and it's terrible for being content, because it walks straight past everything that's working.
So we live surrounded by good we no longer see: the people who showed up, the body that mostly works, the ordinary safety of a normal day. Not because we're ungrateful — because it's quiet, and the mind only notices noise.
Gratitude isn't pretending things are fine. It's aiming your attention, on purpose, at the part of the truth you'd otherwise miss.
