The 80 20 rule


When you use only 20% of your clothes but for 80% of the time, or let's say you have a set of keys, out of 20% of the keys you use for 80% of the times. This is the 80 20 rule. The rule was invented by the Italian economist, Pareto, that observed that 80% of income in Italy went to 20% of the population. The principle rule is that 80% of the effects come from 20% of the causes. I learned this rule in micro-economics class during my engineering studies, and I find it to work in many situations. For example, from all of my clothes there are some that I like the most, and therefore I wear them more often than the rest. Try it yourself...

Yaniv ? I think I understand what you were saying. Is'nt the scenario when a women buys 80 pares of shoes and wear's them 20 percent of the time ?

You are close, Bogie.
I'll use your example to explain so maybe Wstefania will finaly get it ;)
After women buy tons of shoes, they were only 20% of them for 80% of the times.
In other words, 80% of the shoes are wasted in the closet, while they use only 20% that they like the most.
