I Can't Get No...Satisfaction.

Do you ever get cravings for things? And no, I am not talking about food.  Like for example, the other day I was leaving work and as I walked through the parking lot a jet flew over my head.  I suddenly had a very strong craving to get on a plane and go somewhere.  This morning I got a craving to be in school.  Law school to be exact.  Other things I crave, rodeos, shooting, Disneyland, dancing....sometimes I just have insuperable cravings for big expensive, impractical, or impulsive things.  I suppose that these unfulfilled cravings make me a better person...right?  Please say yes.
