Depending on your age, you may be worried about your income in your later years. It seems there is quite a scare that Social Security may not be around some 30 years from now. And even if it is, with inflation, it probably won't be enough money to survive, especially if you end up alone.
One thing you can do today is invest and make your money work for you in your later years. There are some promising stocks that pay dividends. Check with a local broker and find out if there is a way to buy small shares, one at a time. Then reinvest the dividends to buy more stock. (You may want to do this in several companies so that you are diversified.) Once you are ready to retire, you can keep the stocks, but start taking the income from the dividends. Just one small way to increase your retirement income.
