“Compounding is the strategy of putting your money in an investment that pays interest, and then taking the interest you’ve earned at the end of the year and reinvesting it with your original stake, so that your interest continues to earn a return, as does your principal. As this process is repeated year after year, your earnings snowball, and your wealth grows. As you can imagine, the longer you allow your money to compound uninterrupted, the more it grows. And if you allow it to compound uninterrupted over many years-the key to successful compounding-it can produce a fortune.”
