Many people spend their days in a frenzy of activity, but achieve very little because they are not concentrating on the right things.

The 80:20 Rule

This is neatly summed up in the Pareto Principle, or the “80:20 Rule”. This argues that typically 80% of unfocussed effort generates only 20% of results. The remaining 80% of results are achieved with only 20% of the effort. While the ratio is not always 80:20, this broad pattern of a small proportion of activity generating non-scalar returns recurs so frequently as to be the norm in many areas.
