Just to clarify, I do want to make clear that I am talking about a legitimate networking/ multi-level business, perhaps with some of the bigger companies that have been around.
Ones that are schemes, scams, etc, I would not, nor could not endorse. Most of those, do tend to end within a year or so, usually because the government catches up with them.
Companies with a sound financial system for making money, however, have endured, and will continue to do so. There are always new people, new ideas, etc. Not all bottom out completely.
If a person works with honesty and integrity, and most importantly consistantly, they can make it. It is for some people, and not for others.
As long as a person does not cram it down anothers throat, and respects others, then I applaud them for doing something that most people just won't. Good for them.
