Excelsior, ever upwards. The joy of the architect in creating and building things, always to strive for more, to strive to always build more and go higher.

And this is also why I understand about people who work in construction, that is the joy in constructing new buildings, and it seems that the goal is to keep building to no end. Thus realize that happiness is not a final state, but the act of creating, actively building more, higher and greater.
