" You talk of our having an idea; we do not have an idea. The idea has us, and martyrs us, and scourges us, and drives us into the arena to fight and die for it, whether we want to or not."
-Heinrich Heine (1797-1856)
When we get a really good idea, we can tell that it is a really good idea because it won't let go of us. We think about it, dream about it, and pursue it until we can make it a reality. It's like the Universe is tapping on our shoulders, saying: "This is it, come on, let's go!" How could we resist?
