Dr. Oz: "You had to make everyone feel special."
FORTUNE -- "Keith Reemtsma was chairman of the department of surgery at Columbia University when I came to New York. He had served in Korea, and the lore is that he's the person behind the character Hawkeye in M*A*S*H. He made me chief resident and mentored me on how to be a leader. He said the hard part of leadership was keeping smart people from killing each other -- you had to make everyone feel special. People at my level were ambitious, vying for positions. He'd take your strength and find a place you could emphasize it, so it wouldn't seem as if you were competing directly with one another.
"I use that today. For example, I try to get my producers to excel at different things. I don't want them all trying to make the same thing because it breeds discontent. Instead, I say, 'You're good at weight loss, so be the best producer on getting people to lose weight.' There were also times I had huge ideas, and Keith told me there is a fine difference between vision and hallucination. Other people have to see your vision and get behind it, or you're wasting everyone's time."
