I always try to say, 'If you want to help the environment, try to do just two things. One, use less of your car. Second, separate your garbage.'

I always run into these Ph.D.s. They write and write and write about sustainable development. Then these guys ask me, 'But, how do you do it?' They are scared to death to do anything.

After working in cities for nearly 40 years, I am telling you that every city can improve its quality of life in less than three years, no matter the scale or the financial conditions.

The design of a city is like a strange archeology.

A city is like a family portrait - you don't tear it up if you don't like your uncle's nose.

If you want creativity, take a zero off your budget. If you want sustainability, take off two zeros.

The car is the cigarette of the future.
