Our TSP/401k money was invested in mutual funds over a 30-year period - no individual stocks - and it did very nicely for us. The only individual stock we ever owned was stock in the company my wife worked at 20 years, stock that was the company's method of profit-sharing. We kept that stock 40 years, the last 20 after she lost her job due to the company closing the factory. That stock paid dividends every quarter, and every quarter, that dividend was increased - the company has paid dividends uninterrupted for more than 100 years. Those dividends were automatically reinvested back into more company stock and so by the time we both retired, that one stock represented about a third of our total investment portfolio. We sold it at that time and put it with our other money into professionally-managed IRAs, and we are drawing a nice monthly income from it. We will never outlive that money. Had we been like so many people we know of our ages and incomes that chose to buy and trade cars every couple of years, took at least one vacation every year, always had the latest gadgets, lived on their credit cards - they lived a lot better than we did. But now that we are retired, our lifestyle has not been forced to change and theirs has.
