The principle named after Vilfredo Pareto spotlights the “law of the valuable few”.
Or stated differently, 20% of the things you try will bring 80% of your success.
There are 2 approaches to applying this principle.
#1 – Try 100 different things, so that you’ll hit upon the 20 that work.
#2 – Try and come up with only the 20 that will work.
But with approach #2, since Pareto principle will be at play even here, only 20% of your ‘best guesses’ will be right!
