Smart Way #48: Start saving and watch your money grow exponentially

How can you make your money grow by itself? Simple: put a percentage of every dollar you earn into an interest-earning account and decide not to touch it.

Interest is calculated on what’s in the account, then you can add that interest to the original amount, or the ‘principal sum.’ When the interest is eventually calculated again, it will be more than the previous interest and you’ll add that to what’s in the account….and so it goes. This cycle of interest and growth is called compound interest.

With the above in mind, I strongly recommend you start your own long-term retirement fund as soon as possible to make the most of your hard-earned money
