"You know exactly where you are with a woodpile. Its share price doesn't fall on the stock market. It won't rust. It won't sue for divorce. It just stands there and does one thing: It waits for winter. An investment account reminding you of all the hard work you've put into it. On bitterly cold January mornings it will bring back memories of those spring days when you sawed, split and stacked as you worked to ensure yourself against the cold."
