Turner often speaks of businesses “creating clarity” to “separate the urgent from the important” to “generate energy.” A voracious reader of business strategy books, he seeks out the famous authors. At Walmart he brought in Jim Collins to help his executives learn how to go from Good to Great. Deepak Chopra got the call to discuss The Soul of Leadership with Turner’s Microsoft colleagues. Within his first few days at Citadel Securities, he gave Carol Dweck’s Mindset: The New Psychology of Success to senior executives. “One leadership guru doesn’t fit everyone,” he said in November.
Turner’s unfamiliarity with the world of finance came out at client meetings, where his repeated use of clichés and catchphrases from the business books he constantly read made for uncomfortable encounters, according to people familiar with the matter. One Citadel Securities executive would warn customers before meeting Turner not to expect any details from him, according to another person.
