Good news for guys on the higher side of his 30s like me: as we age we tend to think we've achieved our life-goals, moreso than women. Note "think" in that sentence: I'm not sure it has anything to do with actual goals, other than deciding that we're happier with where we are at the time. That 'cup-half-full' attitude has quite a bit to do with being in a relationship, although women don't quite get to that point like men. Women however, are happier when they're independent and young. ;
