One-Line Reality Check for Any Big Decision

You are about to commit to something significant and you want a quick sanity check before you do, not a fortnight of agonising. State the decision in one sentence and this asks the one question that matters, what would have to be true for this to be a mistake, then lists the most likely answers. For when you need a fast, honest gut-check.
