Honestly speaking, it was more like, “Yes, I know it’s impossible, but if I had a gun to my head or contracted some horrible disease, and I had to limit work to two hours per week, what would I do to keep things afloat?” The 80/20 principle, also known as Pareto’s law, is the primary tool in this case. It dictates that 80% (or more) of your desired outcomes are the result of 20% (or less) of your activities and inputs.
