The top 20 percent of salespeople make 80 percent of the money, and the bottom 80 percent only make 20 percent of the money.
Again, the top 20 percent of salespeople make 80 percent of the sales and 80 percent of the money. The bottom 80 percent of the salespeople only make 20 percent. Your mission is to decide to join the 20 percent and then learn how to get there.
In every large sales force, four or five people out of one hundred make as many sales and earn as much money as well the rest put together.
