As an architect it is very important that you distinguish between different realities. There's the reality of the drawing and the reality of the building. So one could say, or at least it is the common belief that architecture has to be built; I always denied that, because ultimately it is based on an idea. I don't ever need a building to verify my idea. Of course, what with a building is more its vanity and actual physical experience. But I anticipate; I wouldn't even build it if I could not anticipate how it would be.
Architecture is not a profession, it is a discipline.
You don't have to become a slave in a corporate office or groupie of a celebrity architect, because all you need is a piece of paper, a pencil and the desire to make architecture.
