Reduce complexity until the decision becomes visible.

Decisions get stuck when there are too many considerations in view at once, and no amount of thinking resolves that, because the difficulty is capacity rather than judgment. Cutting the options, setting aside the factors that barely matter, and stating the choice in one sentence usually makes the answer visible without any new information arriving.

When you cannot decide, reduce rather than gather. Drop to two options and name the single thing that matters most. If the answer is still unclear at that point, the two are probably close enough that either would do.
