A good city is like a good party - people stay longer than really necessary, because they are enjoying themselves.
Something happens because something happens because something happens
I find it striking that the quality of the urban habitat of homo sapieans is so weakly researched compared to the habitats of gorillas, elephants, and Bengal tigers and panda bears in China…you hardly see anything on the habitat of man in the urban environment.
Make it nice where you are, and put the density on top.
A good city is like a good party. People don't want to leave early.
First life, then spaces, then buildings - the other way around never works.
