From Nathan Heintz at Reos Partners: Usually, when we think of limits, we think of restrictions that hold us back, impeding our free energies; we think of what we cannot do. In fact, limits are necessary characteristics of every phenomenon, person, organization, and creative pursuit. Limits, edges, and boundaries are the determining factors that give things their appearance, structure, and definition.
Limits also abound in our minds. Here, they are the criteria that we use to shape the course and content of our work. Limits give us focus, simplicity, and the narrowness necessary to create impact and leverage. In this way, limits enable rather than hinder the creative process. In the case of art, you limit yourself when you choose your materials; in writing, when you choose your subject matter; in building, when you choose a site. Limits are simple reflections of our choices and our particular channels for action and thought. As such, they are not to be avoided or barged through, but worked and collaborated with, tested, and known. Limits create space. Without walls, you have no room in which to work, no container for the substance and content of your work.
