"The secret to success in investing in one word: compounding. The beauty of investing is that you get to compound gains upon gains. Over time, that adds up to outsized returns — but only if you allow time to work in your favor. Consider a simple portfolio that yields 8 percent a year. Over 30 years, the money will multiply tenfold. That’s the power of compounding."
I think friends here are all aware of the power of "compounding", but getting the yields 8 percent a year is a challenging tasks indeed.
