Architects and entrepreneurs are dreamers. They have big ideas but can't bring them to reality without perserverance, collaboration and often compromise. In this new book, The Architect Says: Quotes, Quips and Words of Wisdom (Princeton Architectural Press, 2013), writer Laura Dushkes, a librarian at architectural firm NBBJ, pulls together wise words on work and the creative process. We've pulled out our favorites in this slideshow.
