I have recently started reading the book "SuperFreakonomics." I came across the term "Cumulative Advantage."
To me, this term has the same level of importance as compound interest. As I write this I am realizing this is a very strong way to become very wealthy. For example, when my savings hits a mark, a percentage gets pulled out and used for other investments. I believe this cycle will eventually lead my wealth creation to high levels. I will have a strong savings base that will grow and assist newer businesses flourish which will in turn do the same.
I recommend this book (I've only read two chapters) and recommend looking into the ideal of using the cumulative advantage to become wealthy!
