Thursday Thirteen: The 80/20 Rule

This 80/20 rule is more formally known as the Pareto principle, named after it’s founder the Italian economist. Pareto observed that 80 percent of the income in Italy was received by 20% of the people. For [tag]thursday thirteen[/tag], I will list down how the 80-20% rule applies to me, my work and my life.
1. 20% of my clothes in the closet are barely worn.
2. 80% of my sales come from referrals from 20% of my existing customers.
3. 80% of my blog’s google adsense income are derived from 20% of popular keywords (i.e. sex education, losing weight, SM Mall of Asia)
