Young people crave self-esteem more than sex

If there's one problem that all parents face, it's how to raise their children so that once they are out from under your roof, they will weather the forces of the world and still stand strong in their faith.
MSNBC has a report on some interesting (and kind of self-explanatory) research on how youth and young adults crave acceptance and self-esteem more than sex or other risky behaviour. They are a generation that craves attention, and we find a fine balance between feeding that and teaching them that the world is not all about them.
More than anything you could do, however, teach your kids that they are loved and accepted. Give them a safe place they can run to when things aren't going well, and know that they will always find someone who loves them and will back them. That legacy will carry on for years after they have left your house.
