 Well, we'll certainly be happy when they're out of that stage. We tell ourselves that our life will be complete when our spouse gets his or her act together, when we get a nicer car, are able to go on a nice vacation, when we retire. Truth is, there's no better time to be happy than right now. If not now, when? Your life will always be filled with challenges. It's best to admit this to yourself and decide to be happy anyway.
