If you have an apple and I have an apple and we exchange apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas.
George Bernard Shaw, 07/26/1856 - 11/02/1950 Erse dramatist, author and Nobel Prize Laureate
You see things; and you say, 'Why?' But I dream things that never were; and I say, "Why not?"
