There’s no point in studying the financial section until you’ve looked into the nearest mirror. Before you buy a share of anything, there are three personal issues that ought to be addressed: (1) Do I own a house? (2) Do I need the money? and (3) Do I have the personal qualities that will bring me success in stocks? Whether stocks make good or bad investments depends more on your responses to these three questions than on anything you’ll read in The Wall Street Journal.
