Jeff Cook, Senior Director Global Equipment, McDonald’s Corp., Romeoville, Ill., sums up his life and career in bits of wisdom, the mantras he’s collected over the years. Not because what’s he’s accomplished or how he’s lived is simplistic but because he moves, thinks and speaks so quickly that he has little time for anything superfluous. Besides, those aphorisms have real meaning. Like the job title he playfully lists on his LinkedIn page— “Head Engineering Wizard” at the “Coolest Job on Earth.”
