A good city is like a good party. People don't want to leave early.
Nothing in this world is more simple and more cheap than making cities that provide better for people.
If you make more roads, you will have more traffic.
A good city is like a good party - people stay longer than really necessary, because they are enjoying themselves.
Make it nice where you are, and put the density on top.
Only architecture that considers human scale and interaction is successful architecture.
