I've seen more people fail because of liquor and leverage -- leverage being borrowed money. You really don't need leverage in this world much. If you're smart, you're going to make a lot of money without borrowing.

Most people who meet my wife quickly conclude that she is remarkable. They are right about this. She is smart, funny and thoroughly charming...
