A good engineer thinks in reverse and asks himself about the stylistic consequences of the components and systems he proposes.
Working is actually a pleasure. It's just very time-consuming. It's a way of life. I find that I can work when I travel and work when I run. There is nothing like, on a rainy day, to work.
Higher ceilings allow the use indirect lighting, which is much healthier and reduces glare.
When I work, I work very hard. When I don't work, I have to do something where my endeavor can totally take me off what I do professionally, like sailing. It takes all your attention.
The architecture profession has lost a lot of its integrity, especially in the USA. The general architect here has no scruples, no ambitions.
