 Well, I've always believed that to be an architect you can build anything, and I guess I look back to many of the master builders who build churches and public buildings and homes and parks. And I think one of the most unique things about architecture is it's a combination of creative abilities and sort of analytical abilities. And in the end, one can learn the profession by road or the things that you need to know to pass exams in the profession. But I think talent is really what separates good architects from the rest of the architects. There are architects who think it's an art, and I think there are architects who think it's a function. There are architects who solve problems and make buildings that stand up and do what they're supposed to do, and then there are architects who make very artistic structures that don't function all that well sometimes. And I'm a big believer that what is really extraordinary and interesting and special about architecture is that it's both. It's the ability to solve complex problems. It's the ability to incorporate the many different fields that affect architecture and the different sort of political groups, financial groups, et cetera, that you have to satisfy and end up with something of beauty. You know, it's interesting to make that comparison because automobiles, we can reduce the need for automobiles. And that's one thing that we have a great ability to control. And I think that's one initiative that we're going to see this change our society vastly. I don't really think we have the opportunity to reduce the number of buildings that we have. The need for buildings is very closely related, I think, to our population growth. So I think that with buildings, we have to look at how to build them in a more sustainable manner. And I think the biggest problem that we face there, at least as architects, I believe that we face, is not enough knowledge. There's so much of what comes to us as information, I think, is vetted by we don't know who. I mean, I'm a believer that you can take almost any building and talk about it as being sustainable if you want to. And we've had to do that a bit because now everyone wants to see that everything we're doing is sustainable. But in fact, we have many clients who could care less about doing sustainable buildings. Therefore, they're not as sustainable as they might be if we had our wishes. So we've, but we can make them look sustainable. And I think in the same way, the products that come to us and the other services that we employ, we rely on whatever information they give us. And I think a lot of that is very sketchy. So I think getting at the truth is one of the more difficult things that we face. Educating our clients, because in the end, we don't make all the choices that are made about how sustainable a building is. Many aspects of sustainability come with great cost. And that is something that affects our clients, and sometimes it's something that gets eliminated from a project because of its cost. So I think educating the world and our clients, and even if that requires some sort of outside pressure, whether that be regulatory pressure, which I think we're starting to see now, I think we'll make those sorts of things change over time. But I think that is a massive responsibility of ours to go beyond what we're being asked to do and to teach our clients what a good building is. And to get them to look at buildings in different ways and get them to do what is sometimes the right thing.
