I gave a quote for this book published by Chronicle Books, containing sayings and advice from a variety of designers and design teachers.
My quote has been featured on the inside cover. In all my time teaching at St Martin's, this is perhaps the most important thing I wanted to get my students to understand: know, and be able to articulate, why you're making your design choices...
It's out now, full of all sorts of good advice, and available from Chronicle Books and Amazon.
