Taking pride in ignorance First and foremost, concentrate on your strengths. Put yourself where your strengths can produce results. Second, work on improving your strengths. Third, discover where your intellectual arrogance is causing disabling ignorance and overcome it...First-rate engineers, for instance, tend to take pride in not knowing anything about people. Human resources professionals, by contrast, often pride themselves on their ignorance of elementary accounting or of quantitative methods altogether. But taking pride in such ignorance is self-defeating. Go to work on acquiring the skills and knowledge you need to fully realize your strengths. Peter F. Drucker, Managing Oneself ignorancearrogance
