That could be true SO2, but I think the problem lies in the fact that they have never found happiness, and that's why they continue to screw up their lives, because they think that next great thing is it. IMHO, only a revelation of the need for God can fill the huge gap that is inside them.
This brought something to mind...when my exh and I were in counseling once he told the counsleor that he knew he had a great wife that loved him, but HE just wasn't happy. So it is a perpetual cycle and we just got caught in the mess.
