Little by little, one travels far.
J. R. R. Tolkien
British scholar & fantasy novelist (1892 - 1973)

The mathematics of repeatedly carrying out a task are astounding. The numbers add up very quickly. For example, if you chose to ride a bike for eight hours in one day, peddling along at an average of five miles an hour, you would cover forty miles. Do this every day for a week and you would cycle 320 miles. In four weeks you would have completed 1,280 miles.

On a larger scale, forty miles a day, five days a week, for an entire year equates to 10,400 miles – or about the distance from London to Sydney (as a crow flies).
