My boss uses the quote above all the time. He’s used it in conjunction with “Put your opinion down and step away from the designer” as he slowly backed away from my cubicle. I laugh, but at the time I knew I was a little fiery with the redundancy of changes being requested. The battle between good design and opinion rages on. Thus, your opinion, although interesting, is perhaps irrelevant when it comes to the philosophy and logic that lies behind good, intentional, meaningful design.
Designers, set your ego down. Non-designers, tuck your opinion into your back pocket and step away.
My boss was a wise man.
