A common mistake that people make when trying to design something completely foolproof is to underestimate the ingenuity of complete fools.
Design must be functional, and functionality must be translated into visual aesthetics without any reliance on gimmicks that have to be explained.
Design is a plan for arranging elements in such a way as best to accomplish a particular purpose.
When I design a wedding dress with a bustle, it has to be one the bride can dance in. I love the idea that something is practical and still looks great.

You can design and create, and build the most wonderful place in the world. But it takes people to make the dream a reality.
