Keep in mind that this is a business ownership opportunity. You don't work for the individual who introduced you to ACN and you don't work for the company. You work for yourself and have all the advantages of owning your own business, such as the equity you build in your business. Your ACN business is willable and sellable at any time, and you have all the tax advantages of owning your own company. 

You may develop customers for all services and earn commissions from the sale of those services as well as build a marketing organisation. The ACN marketing plan is very flexible. It provides you with a number of opportunities for advancement. You can begin with a small personal customer base and build it larger over time, or you can develop your own marketing organisation and earn an override from the efforts of everyone in your organisation. Most people choose to pursue both, adequately rewarding themselves for their time and effort.
