Cathey Armillas is a marketer, speaker, and author of “The Unbreakable Rules of Marketing” and “How to Rock a TED Talk.” Cathey is a speaker coach to me and some of the best TEDx speakers I’ve seen, including a bunch of our entrepreneur friends. What touched me the most about Cathey’s life story is the inspiration and profound love she has for her younger sister, Karen — a sister who showed up for her again and again through Cathey’s dire moments post-divorce or roller-coaster emotions starting her own business. All of it.
