I’ve put so much into this. Is that a reason to keep going?

I’ve put into . Seeing it through would take . Help me judge only what’s still ahead. First, list what’s already spent and can’t be recovered whether I stop or continue, and set it aside. Then compare the road from here: what continuing will cost, what I’d realistically get from finishing, and what else that time and money could do. Then tell me whether someone handed my exact position today, with no memory of what it took to get here, would pay what’s left in order to finish. Don’t comfort me about what’s spent, and say what you’d need to know to be more sure. Be direct. No padding and no reassurance I did not ask for.
