80:20

Especially Entrepreneurs start running into time constraints when trying to service all customers ion the market, but the same is true for mid size and companies and even humongous corporations.
The idea is that the more clients you can obtain the more money you will make.
Well if you think that i have to tell you that you are wrong in most cases. the truth is that the economic 80:20 rule holds true to almost all situations. It indicates that 20% of your clients will give you 80% of your profit.
The question than is why are you wasting 80% of your time with the remaining 20%???

For example assuming you are are sales person for IBM and you currently have 10 clients. The 80:20 rule indicates that your have 2 good customers that bring in the wide majority of your profits while the remaining 8 clients are essentially wasting your time.

what is the conclusion? Well I warn you it is a little bit scary but try to get rid of the 8 time wasting clients (sell them to co-workers or even competition) while focusing 80% of your time to find 1 or maybe 2 more clients like the 2 that previously made you 80% of your profit. It should not be too difficult to come up with one new client and guess what one new "good" client will make you twice as much profit as the 8 you had before while only needing an 1/8 of the time.

Try and follow that rule for a couple of month and watch your profit margin increase and your wasted time diminish.
