Most financially successful people get that way not through business innovation but through compound interest on their savings and investments. A simple example: If a 22-year-old invests $1,000 on January 1 at 7% per annum, next year the investor will have $1,070. In 10 years, the investor’s initial $1,000 would grow to $1,967. Upon retirement, at age 65, that single initial investment of $1,000 will have grown to $18,344.  

Amazing.
