I think Khan is being a little too cautious. However, being a millionaire, he probably is more careful to instill certain values in his children, since they'll never do without for lack of money. I often read on the internet about how parents too often praise their kids for being smart, but I've never seen this in real life (except for my children, who are brilliant ;) I wouldn't take the research literally. I think people should take all the good lessons learned from their parents, along with some common sense, and pass them on to their children.
