The Talmud explains this with an analogy of donkey drivers. In Talmudic times, the drivers used to charge one coin (a "zuz") for traveling 10 miles. If they were asked to travel 11 miles, they charged an additional zuz for that one extra mile. One zuz for 10 miles and two zuz for 11 miles would seem to be a disproportionate increase. However, that "extra mile" exceeded the donkey drivers' customary practice and was, in essence, equivalent to all of the preceding miles.
That which requires effort, the "one extra" that calls for an inner struggle, is what it's all about. The little extra that we do to go above and beyond can be worth as much as everything else we did up until then.
This brings up the classic debate of effort versus performance.

In the "olden days," it was standard practice for a person to review his Torah studies 100 times. (Try telling that to the kids when they complain about studying for tests!) If a person reviewed his studies 101 times, he was deemed someone who went above and beyond the expected and the 101st time the material was reviewed was considered greater than all of the previous 100 times put together. Why? Why would learning something one more time after you already studied it 100 times help at all? We can answer that question with an example of a donkey.Donkeys Going the Extra Mile
