When John Mackey co-founded Whole Foods, he didn’t consider himself an entrepreneur. But after 42 years of leading the company – and spearheading its sale to Amazon – Mackey has proven that a business with purpose can succeed and scale. John speaks with Adam at an Authors@Wharton live event about his Whole Foods journey, from living in his first store to selling the company. They discuss the pros and cons of 5-year plans, strategies for staying flexible and adaptable, and the role of passion in a career. Transcripts for ReThinking are available at go.ted.com/RWAGscripts.
