Mistakes are the price of admission of learning or as Thomas Edison once said “I have not failed. I’ve just found 10,000 ways that won’t work.”  – Dad

The 80-20 rule, also known as the Pareto Principle, defines how causes and outcomes correlate. It states that 20% of causes drive 80% of outcomes.

Interestingly enough, 80% of all profits likely come from just 20% of your customers. The lesson here is don’t try to be all things to everyone. It will dilute the effectiveness of serving your most important clients. – Dad
