More than just one discipline...
Remaining solely focused on your design discipline can make you exceptional at your craft. This very focus, and attention to detail can propel you to new heights in your career. However, a singular creative endeavour can encapsulate us within the box that we fear the most.
As a creative person you probably have several creative interest in addition to your main creative focus. For example, you may be an architect, but also enjoy cooking, drawing, photography, dancing, and a plethora of other engagements. These extra creative engagements may not be your focal point, but they are an extension of your unique capabilities. Neglecting these small outlets may actually dampen your main endeavor in the long-run.
