One of the silly things I see around some forums, and what I remember from my Amway days is hearing about how someone "made the decision" to go diamond. You cannot "decide" to go diamond anymore than you can decide to win the lottery. You can decide to work hard and you can decide to try and follow all of the recommended advice for achieving diamond in Amway, but you cannot "decide" to go diamond. Going diamond requires you to have certain group structures with certain volume requirements, which requires sponsoring. Sponsoring others is something that is not directly within your control. And it is certainly not under your control when you need multiple downline groups to sponsor people as well. Maintaining retention in your group is also something you may not have direct control over. All it would take is one downline group to have a falling out with a mass exodus and your qualification for diamond can vanish in a day.
One familiar theme I recall hearing on WWDB rally tapes is that someone, usually the man of the house, finally made a decision to go diamond. I don't recall a detailed explanation of what that actually meant. When I was prospected into Amway, my sponsor never could tell me in a straight answer what you actually do as an IBO. All he kept assuring me of was that I could be taught everything I needed to know. Looking back, he was right. In a nutshell, the Amway business is simply this: Buy, sell, and sponsor. But of the three components, the only one an IBO can directly control is to "buy". To sell or to sponsor is something that you have no direct control over because it involves the decision of other people.. Yes, some people can improve and get better at selling or prospecting, but I believe the vast majority of people, even those who work hard and give an earnest effort, simply do not have the skills to overcome the bad reputation of Amway and premium prices (for generic in nature products)that apparently stigmatize the Amway business.
As I have stated, you can decide to try Amway. You can decide to buy tools and products. You can decide to work hard and give your best effort. You can decide that this is a good opportunity for you. But you cannot decide that you will go diamond. Many have tried, very very few have made it. In my old LOS (WWDB), there are fewer diamonds now than when I was an IBO. And there have been very few new diamonds in the US and Canada. Even those who attain the apparent pinnacle of success (diamond), often find that maintaining the level is a near impossible task. There is evidence of many former diamonds and diamonds who actually quit. Where's the residual income that IBOs like to speak of? Why would someone quit if they can walk away and receive residual income. You know why.
Good luck to you if you "decide" to go for it.
