I'm an optimist by nature. In the glass-half-full, glass-half-empty debate - I'm the guy who is happy there's a glass.
When I served as Speaker of the California Assembly, even during the energy crisis, I kept in my office a framed copy of Alexander Graham Bell's quote: "problems are nothing more than opportunities in working clothes."
So why is it that even an optimist like me wakes up these days with a pit in his stomach?
