i think you can have too much of a good thing. too much of one thing can send people crackers (medical term). the same way people who are down on the luck for a long period go mad...........living in 'good thing' world may also send you bonkers.
I've never actually HAD too much of a good thing, so I'm thinking it's one of those urban myths.
