All roads lead to Rome

All paths or activities lead to the center of things. This was literally true in the days of the Roman Empire, when all the empire's roads radiated out from the capital city, Rome.

Many different methods will produce the same result. For example, So long as you meet the deadline, I don't care how much help you get—all roads lead to Rome. Based on the fact that the Roman Empire's excellent road system radiated from the capital like the spokes of a wheel, this metaphor was already being used in the 1100s.
