There is no money made without a risk taken. Whether it’s starting a business or investing in stocks, every avenue to making money requires some risk. Even selling your old furniture requires you taking the risk that the buyer will show up and will pay you. It is a comparatively small risk when compared to deciding whether to spend millions of dollars on a new product line, but it is still a risk.
Just wondering how many people you know personally, that saved and invested, especially if they made minimum wage, weren’t college educated, had a family to support, etc. and became as you say, ‘filthy rich’ by following the principles of this page? People read simple-minded articles and poor things, if they are simple-minded enough to believe the garbage.
