Last month, I wrote about the rising recognition of emotional intelligence as a key factor in successful leadership using the new movie "Inside Out" to illustrate points about anger and self-management. Now, I turn to "The Sound of Music" for an assist in addressing another competency of emotional intelligence: self-confidence. In the movie, young novice Maria tentatively begins her journey to be governess to seven children. She has no experience and is forced to leave everything she knows. In the song "I Have Confidence," Maria sets her intention for how to handle the new situation, telling herself that she will stop self-doubting, be firm but kind, face her mistakes, and earn respect, adding that, "While I show them I'll show me." The "me" part is key. In this way, Maria employs positive self-talk to overcome her lack of courage, acknowledging that the most critical person in the self-assurance equation is herself. So when she later encounters obstacles—the heavy gates of the mansion she must physically push open, coldness of staff members, pranks played on her by the children and her seemingly cruel new boss—she need only look within for confidence.
