In Cities and the Wealth of Nations, Jane Jacobs quotes a Japanese economist about his country's capitalist revolution following the Meiji Restoration. He said that the greatest periods of creativity and productivity had been experienced when the country was adrift, not focused on any particular goal but open to all opportunities.
Urban planners, particularly Americans, identify with the maxim "make no little plans" attributed to Chicago plan architect Daniel Burnham. According to this idea maximum effort should be focused on a single, enormous goal, and a concensus should be built around this goal in order to achieve it. This is how the Chicago plan was realized, and this has been the frame upon which nearly every urban plan continues to be modeled. New innovations, like the charette process, are only refinements of the paradigm established by Burnham. To someone focused on a single large-scale goal small-scale problems like a complicated permitting process or bad street design are irrelevant. Someone focused on a single large-scale goal does not see any drawbacks to using repression to realize the plan, like zoning and urban growth boundaries. The city they envision does not have a small scale, and this is now the reality of our landscape: urbanization at enormous scale, with no concern for details and no sustainability.
A creative city is not goal oriented. Not only does it make little plans, it makes millions of little plans. It is adrift looking for its next opportunity. It is not made by an architect, but cultivated by its people.
Make millions of little plans.
