It's essentially only as good or as bad as you are. Lots of people lose friends from going too far with these programs. The key will be to find a balance between being a good salesman and being a good friend. Don't let money corrupt you. It happens a lot. You enroll a few of your friends and family under you, and suddenly you change roles from friend/family to boss. Do they perform well? You make more money. Do they not care as much as you do? How do you handle it? Are you going to constantly hit up your friends and family for sales? It'll be important to separate business from pleasure. Most people assume friends and family are quick and easy money, but you only lose in the end. Stick to soliciting strangers, I say. You can get money with any job. You can't buy friends and family. If you do MLM carefully, there's no problem. It's easy to be corrupted. Just be careful.
Making limitless possibilities much more limited.
