“One thing you’ll notice if you spend very much time talking with Sam about Wal-Mart’s success. He’s always saying things like ‘This was the key to the whole thing,’ or ‘That was our real secret.’ He knows as well as anyone that there wasn’t any magic formula. A lot of different things made it work, and in one day’s time he may cite all of them as the ‘key’ or the ‘secret.’ What’s amazing is that for almost fifty years he’s managed to focus on all of them at once—all the time. That’s his real secret.” —DAVID GLASS
