[책]A More Beautiful Question by Warren Berger

"... questioning is seen as 'inefficient' by many business leaders, who are so anxious to act, to do, that they often feel they don't have time to question just what it is they're doing"

"... expert is someone who has stopped thinking because he 'knows'"

"We think someone else - someone smarter than us, someone more capable, with more resources - will solve that problem. But there isn't anyone else"
