Some designers take great pride at being an a-hole. I was speaking with a designer I'd never met before, and he boasted for quite awhile about his take no prisoners attitude. He told me a story about yelling at a young designer at his firm during a client presentation until she cried. He loved to invite freshly graduated designers for an interview and then tear their work apart piece by piece.
While this sounds like an interesting reality show, the result is simply hurt and terrified designers. It doesn't make anyone better. Unless someone shows up with a heroin needle stuck in their arm, there really is no reason for berating until tears in design. The profession is hard enough without that.
I'd rather take my cue from Gene Frederico. Frederico was one of America's most revered art directors for decades until he died in 1999. He was passionate about good design, and certainly never let anyone slide by with less than their best. Yet, he took time to see young designers and critique his or her work in a constructive way. Most designers at his level could simply pass this task along to someone else.
Frederico's work is witty, fresh, and bold. It never feels overwrought or desperate. He used typography as illustration. Frederico named A.M. Cassandre's poster, S.S. Amsterdam, as a great influence on his career. His work meets Cassandre's high standards of flawless shape and form, but takes it one step further, always adding that smart and unexpected concept. His moving announcement, that depicts everyone moving, is a perfect example of his dry humor and incredible skill. To paraphrase a song by the Burning Sensations, Gene Frederico Was Never Called an Ass-hole.
