On a coast path the next headland hides the one after it. You walk for an hour and the view barely changes, then you round a corner and the bay you started from is a shape in the far distance.
Plenty of days won't feel brighter at all; the unit that matters is the one that feels like nothing while you're inside it. Direction is what's being claimed, not the quality of any given Tuesday, and the evidence for it sits behind you — the bay you could no longer walk back to in an afternoon.
