Then you have the clients. The care and feeding of clients is really one of the main obstacles, because you always have a client with some preconceived idea of what a house looks like, and all you want him to do is leave a check and go to Europe for a couple of years. Or leave two checks. But alas, life isn’t simple. If it were, more people would be better architects.

But, of course, we had one problem that the modern mountaineer doesn’t have. That is, this psychological barrier. We really didn’t know whether it was humanly possible to reach the top of Mt. Everest. And even using oxygen as we were, if we did get to the top, we weren’t at all sure whether we wouldn’t drop dead or something of that nature. All the physiologists had warned us that the altitude at the summit of Everest was a very marginal altitude and might be extremely dangerous. So, one had this feeling in your mind all the time that maybe you were pushing things a bit beyond what humans were meant to do and you couldn’t ignore that feeling. But, because of strong motivation, you keep plugging on and you seem to be going okay and nothing seems to be going wrong, so you persist. And we persisted, of course, and ultimately, set foot on the summit.

In terms of this issue of these industrial gases affecting the environment, at the beginning the road was not easy, because we were suggesting that society had to change, that industries had to do something different than they were doing at that time. And of course, initially we did not meet with a good reception to these ideas from industry. And even from the scientific community — even though our ideas were well received in the small group of specialists in what we were doing — it was not necessarily well received by the scientific community at large. So we really had to continue doing as good a science as we could, and at the same time trying to well communicate our conviction that it was something important, something that had to change in the way society was functioning.

There were lots of times, especially in the early days, that were very, very difficult. I think the most difficult experience I had was in 1990 when Oracle had its only loss quarter in history. We’d been in business for 20 years, and after 20 years we lost money one quarter. We had a very difficult time. We had virtually doubled our sales every year for ten years. Nine out of ten years, ten out of eleven years. It was really quite an amazing run. We were the fastest growing company in history
