My mom sold Amway for years, but only to a few neighbors that liked the fact she didn't try to "build the downline". Her sponsor was a gem.
I had a couple that I felt were friends call me some 25 years ago, inviting me to dinner to discuss a business proposal. I was mildly surprised when instead of heading to a local restaurant, they chose to drive nearly 25 miles to some steak house. Nice dinner and conversation, and just as I'm about to ask when they intend to start talking about the proposal, they tell me it's time to head to the meeting. Which turned out to be another 25 miles further from home. Turned out to be a big Amway meeting. Yes, you can make big bucks in Amway, but you really ought to try and attend one of these meetings and see if it's the sort of thing you want to involve yourself in. The folks running things seemed a cross between patent medicine pitch-men and old time religious revival preachers, with money being the apparent object of worship. My by now former friends kept me there until 11pm and outright turned on me during the hour drive home. How dare I enjoy a dinner and evening with them and not sign up!
I did sign up under another friend years later, just so I could buy the products at cost. I like the products btw. Well, ol' Bob soon went back on his "I'm low key about this" approach. Kicker was knocking on my door at 12:30pm (yeah, that's after midnight...) to hand me a brochure for a Mercedes 190 and telling me how good I'd look driving one!
You can make money, and lots of it. Maybe. To have a shot at doing so, you will have to make it your total lifestyle. Forget about machine auctions, fixing and making things, etc. Your social life will come to revolve around your upline and downline.
Sounds like I'm knocking it. Not really. It's just not my thing. I'd be surprised if anyone active in metalworking here is also heavily into Amway...
