Network marketing, a business model within the direct selling industry, is growing faster than any other industry in the world. An estimated 15.2 million people are involved in direct selling in the U.S. and more than 59 million worldwide. The vast majority are independent business people - they are micro-entrepreneurs whose purpose is to sell the product and/or services of the company they voluntarily choose to represent - not employees of the company. Approximately 90 percent of all direct sellers operate their businesses part-time. They enjoy flexible hours, high levels of personal satisfaction and near limitless income growth potential.
