You have most likely heard of this rule, by one name or another. It's also known as the 80/20 rule, factor sparsity or the law of the vital few. It simply refers to 80% of your productivity stemming from 20% of your activity when allowed to adjust naturally. When it comes to earning money online, think of it as 20% of the programs you participate in usually supply 80% of your income or contacts. In the case of Network Marketing to build a downline of any kind, 20% of your referrals are going to supply 80% of your growth.
Once you understand that principal, it starts to become obvious that it can be controlled and improved with careful analysis and pruning. Just like growing a grape vine, if you prune the unproductive branches to allow more nutrients to reach the parts that produce more, your yield is going to increase naturally. Doesn't the same thing make sense in any kind of Internet marketing?
