There's a sign up in my home office that says "When opportunity knocks, don't be in your bathrobe." Words to live by! And in a related idea, the words of William C. Martell, screenwriter and dear old friend: "Take my advice-- I'm not using it." (Don't worry; I'll explain later).
One more thing.
Never enough. Never enough time, never enough accomplished, never enough.
But, onward we go.
