Network Marketing is teaching and mentoring others
Look at the actually words of Network Marketing. Network - talking to other people. Marketing - usually involves a product or service. I don't see where anyone would come to the conclusion that network marketing is about teaching and mentoring others.
Teaching and mentoring is definitely a part of the service that comes with successful network marketing but "Network Marketing" is not about teaching or mentoring.
If you are new to network marketing, I am very sorry you are being taught a very erroneous mindset.
To your success,
