All of these boil back down to two words. These two words are the root cause of over 90% of the MLM failure experienced in the world.
GREED AND EGO!
Be it with the company or the upline, if Greed and Ego get in the way, failure is certain. Remove the agenda, make it ALL about the people, and success will come much easier.
If you primary motivation is the money, you are making a mistake. Put people first and let everything else fall in place from there.
