I agree more with the more contemporary ideas of shared leadership. I believe that every one has some form of leadership qualities, whether they're obvious or subtle. Some people can simply lead by quiet example. Everyone has unique qualities that are useful in different situations. No one is good in every situation. When a team of people get together and just be themselves, each person has something to offer and together they form a successful leadership group. Some people can even lead as followers--by being hardworking and being able to follow through to get tasks done.
In high school I was a part of a dance competition team. We worked together and had a system to our practices. We had specific practice days and times, and there was order to the routines we worked on. In order to be a successful team we had to have order. However, flexibility took a huge role in our team, because things never went as planned. We had to be able to adapt to new situations and places when we went somewhere to compete. Also, we had to be able to re-block dances if a girl was sick or injured. Injuries caused the entire dance dynamic to change, and we all had to be able to be calm and positive when things occurred that were beyond our control.
