Averages...

Averages are pretty simple - doing something above the average raises the whole thing, doing something below it brings it down.

With a score on a test it’s easy to calculate the effect on the average (and to see how you compare), but with something more abstract, like a day, the effect can be a lot more difficult to work out.

The odd below-average day won’t make that much difference over a whole life, but putting in the effort to try and make every day better than the last ? There is only one way that that average is going, and it sure as heck isn’t down…
