Albert Einstein wisely said, “Compound interest is the eighth wonder of the world. He who understands it earns it… he who doesn’t… pays it.” Compound interest is what time gives your financial investments. It is the exponential growth of accumulated interest over time. It is essentially free money awarded to those who start investing while young. In the same way that this principle works in finance, I believe that happiness compounds. Happiness is awarded to those who start living their what if while young.
