Economically, you can think of a network marketing business as a ‘Startup’.
Venture capitalist, Paul Graham explains, that a startup is a way to compress your whole working life into a few years. Instead of working at a low intensity for forty years, you work as hard as you possibly can for four. Doing this pays especially well in network marketing, because you get to build equity and scale your impact, right from the start. I.e. a network marketing opportunity can serve as a springboard toward your financial freedom which can allow you to pursue your dreams or a greater purpose with more freedom.
To build a business that can give you time freedom, you basically need three things: First, you need a great idea, that is novel and useful. I.e.: something that people want. Second, you must be able to scale or leverage your time spent on the business or project. And third, you need access to funding to start your business. This could easily be millions of Dollars.
In network marketing though, you have access to an idea or product that is already developed and proven. Your startup capital is negligible in comparison to a traditional business. The business model is designed to help you create leverage right from the start. Furthermore, you can start part-time and you don’t need to quit your job until your income matches your daily needs.
not all opportunities are created equal
There are many Network Marketing opportunities in this world. How would you choose one that will trump the rest and endure?
Firstly, it would be wise to be positioned within a growing market. Wall street investment banking firm, Goldman Sachs, states that the health/wellness mega-trend is one of the most visible social developments across the globe and represents one of the fastest growing segments of the market, namely the natural/personal care, functional foods and nutritional supplements arenas. Furthermore, Goldman Sachs says, while the standalone prospects of the health and wellness and the direct selling industries are strong, an even more powerful vehicle is created when the two are combined...The lack of information about vitamins and other supplements is apparent. In many retail settings, shelves are overcrowded with multiple varieties and brands of similar product, and non-knowledgeable salespeople do not facilitate the shopping experience...In addition, there is no better advocate for a nutritional product than the user his/her self. Once someone’s life is changed due to the product, strong loyalty can be created both to the product and to the business opportunity. 
According to world renowned economist, Paul Zane Pilzer, only 20 companies will share in 80% of this market. Let’s put this in perspective, if it grows to be a 2 Trillion Dollar industry, each of these 20 companies have a chance to be as big as Apple is today (2015). But since it is still early days, and the companies that offer the real value are yet to present themselves, Paul Zane Pilzer offers three criteria on which to base one’s decision: 1. Scientific Validation. 2. Patent Protection and 3. Disruptive Technology. 
Mannatech, Inc., a 22-year old company based in Dallas, TX, and listed on the NASDAQ stock exchange, seems most likely to fulfill this criteria. This may present an unprecedented opportunity for emerging entrepreneurs as a springboard toward success.
This is the only company to have pioneered a new field of science, Nutritional Glycobiology. MIT (Massachusetts Institute of Technology) declared glycobiology to be one of “10 emerging technologies that will change the world.” 
Mannatech boasts 115 patents issued, granted and validated in major global markets. This is certainly unique for a company in this field, as most companies in this industry have few or no patents. This also demonstrates the dedication and importance Mannatech has given to creating unique products for audiences in major global markets. 
To further disrupt the market, Mannatech also developed the nutrition industry's first supplement containing fully standardized and completely plant-based vitamins, minerals and phytonutrients. Mannatech offers the best alternative to synthetic vitamin and mineral products and so-called "super-juice" products. 
But the value of a patent only becomes evident once it is successfully defended in a court of law for patent infringement. To date, Mannatech have been granted injunction on patents infringed by more than 20 companies. 
Additionally, Mannatech’s broad portfolio of patented products has been validated by research conducted by independent scientists and published in peer-reviewed scientific journals. Currently, 17 human clinical trials have been published, 13 of which were double-blind, placebo-controlled studies — the gold standard for product validation. 
A disruptive technology is something, not seen coming by the masses or powers that be, that literally puts existing technologies out of business and spawns whole new industries.
Mannatech might just be the industry’s best kept secret.
But I don't want to sell to my friends
This is true of anything in life, but when you know that you found something of value, you feel compelled to share. Because of Mannatech's robust scientific approach, and the results people get, entrepreneurs can have confidence that they bring real value to their network.
Another advantage that brings meaning to this opportunity is the fact that Mannatech is the first company to fight the cause of malnutrition, on a global scale, through the means of social entrepreneurship. In 2014 Mannatech registered as a Social Entrepreneur company and is leading the way toward a more meaningful impact. These organizations are neither businesses nor charities, but rather hybrid entities that generate revenue in pursuit of social goals. This desire to blend purpose with profit has more recently been formalized in structures such as the US “benefit corporation” (B Corp), a corporate entity legally required to create benefit for society as well as its shareholders.  In Mannatech, every product sold generates a donation to a child in a feeding program or orphanage. It's a way to bring sustainable change. Everybody wins, not just the shareholders: The entrepreneur wins by sharing in the increased revenue and building equity alongside the shareholders. The customer wins by receiving a real food nutritional product that has no equal in the industry. A malnourished child wins by automatically receiving the world’s most advanced nutritional supplement, for free.
on pyramid schemes
In his book, "The Next Millionaires" world renowned economist Paul Zane Pilzer, explains how old models of opportunity in physical distribution have given way to new opportunities in intellectual distribution, defined as teaching people about products or services that they didn’t even know exist. This is evident especially in direct selling, network marketing, technology, home-based business, product distribution, and the emerging trillion-dollar industry of wellness. Pilzer believes that this form of distribution will become a leading form of distribution. 
Potential customers may still not understand the difference between a ligitimate network marketing business and a pyramid scheme. Best selling author and millionaire, Robert Kiyosaki, says he is often asked if network marketing is a pyramid scheme. His reply is that corporations are really pyramid schemes. A corporation has only one person at the top, generally the CEO, and everyone else below. A true network marketing business is the exact opposite of traditional business model. The network marketing business is designed to bring you up to the top, not keep you down at the bottom. A true network marketing business does not succeed unless it brings people up to the top. 
By starting a network marketing business in your spare time and keeping your regular job, you begin to gain the tax advantages of the wealthy. A person with a part-time business can take more tax deductions than employees can. E.g. you may be able to deduct car expenses, fuel, some meals and entertainment. Even a part of your home expenses as you will work from home. 
the challenge of a lifetime!
Network Marketing businesses are not magic like some would have you believe. They don't change the laws of wealth creation. It just represents a point at the far end of the curve. Success is earned through diligence, enthusiasm and the right product combined with timing. Being an entrepreneur and building a large business is one of the toughest challenges a person can take on. The reason why more people are working as employees, or are self-employed, is simply because those are less demanding than building a business. As they say, “If it were easy, everyone would do it.”
Robert Kiyosaki says, you will learn how to overcome self-doubt, shyness and fear of rejection. You will learn how to pick yourself up and keep going after you failed. Another important skill is leadership, being able to overcome not only your own fears, but inspire others to overcome their fears to get the job done. These are some of the personal traits a person must develop if they are to be successful in any business endeavor. Most schools and MBA programs train students, not to be successful in their own businesses, but for high-paying jobs in the corporate world, still trading their time for money. Where can you find a business that will invest the time in your education, your personal development and help you build your own business? Robert Kiyosaki responds and says, "The answer is: network marketing."
