I didn't regret it, though.
MLM/Network marketing is just like any other business. You need a good middleman (rather, middlemen) to run the business for you.
For example, you plan to run a restaurant. You need a competent accountant, a good cook/chef, skilled waiters/waitresses, cashiers, utility men/women, etc. It works the same way with network marketing/MLM. You need competent people who can recruit other competent people and/or sell the products. The most important part is the monitoring. You need to know how to properly manage your personnel, like any other business actually. Make sure that everyone is moving and making your network grow as much as possible.
I'd like to call MLM/network marketing "delayed gratification." You'll need to make a lot of sacrifices if you want to become a top earner.
