Kids will keep it real. If I've ever had in my life a great anchor it's them. They get in your head 'don't get too famous.' If you think you're really famous and think you're really hip go hang out with your kids for an afternoon. That's about as earthbound as it's going to get.
I believe in the institution of marriage. Of course being a Mormon we believe in eternity rather than just till death do us part. If you really try hard if you make it work it's blissful. But I also know a marriage that isn't working can be painful.
