Good design is as little design as possible.

"I have spoken of our surroundings but let us look at the wider environment: the world we live in. There is an increasing and irreversible shortage of natural resources: raw materials, energy, food, and land. This must compel us to rationalize, especially in design. The times of thoughtless design, which can only flourish in times of thoughtless production for thoughtless consumption, are over. We cannot afford any more thoughtlessness."  -Dieter Rams, 1976 from Fast Company
