Another time, you might pull your child close—don’t delay, because most smokers start between the ages of eight and 14—and say, “See that nice young man over there with his collar up in the wind, smoking outside that building? They won’t let him smoke inside, because a lot of people don’t like smoke, and his family is probably worried that he might get sick someday—but forget all that. Here’s his real problem. Those cigarettes he’s become addicted to cost him $6 a day. By now, he’d probably like to quit smoking, but it’s very, very hard to quit once you start. So he gives the tobacco companies $6 a day and probably will for the rest of his life. But if he hadn’t gotten hooked, or could somehow quit, and put that $6 a day into a mutual fund at 7% instead, he’d have an extra $2 million by the time he’s Grandpa’s age.
