Author Richard Koch says that we will get 80% results from our specific 20% of works. Suppose if someone is doing a business then he will get 80% projects from his specific 20% clients. Whatever client base he has but the potential client will be 20% of them.
So the same thing is happening in our works also. We are getting 80% returns on our specific 20% works. So we have to identify that 20% to keep the focus on that.
Also, you will get 80% complains from specific 20% of your buyers.
Most of the times the people who want to start a business is focusing on some unnecessary things. They are spending too much time to make a website or a logo. They are more conscious about the design of their business website. But the fact is that they can easily buy a Premium WordPress Theme or Premium Bootstrap Templates to set up their website.
To know more about this rule you can buy the book 80/20 Principle: The Secret to Achieving More with Less – By Richard Koch.
