The answer to question 3 relates to this question too, but there is more. It isn't always the best at doing something who makes the best leader. One of the universal characteristics of leadership in most cultures is the willingness of leaders to have emotional connexions with their teams. Being nervous about a particular task, whilst getting on confidently with what needs to be done, is an even more powerful act of leadership if you allow those close to you to share in the way you feel. It is your humanity that inspires others, and your courage to face your demons that makes them want to confront their demons too.
