leadership - are leaders nessesary?

   I got this thought from the final exam. I believe that leaders are necessary to create a functioning group. This can be anything from a single leader to a group of leaders. With no leader in a group nothing will take place. A leader does not necessarily take take full control of the whole group, but a leader or multiple leaders will have to step up to the task. Each person may have a different role to play, and even though they may not be telling others what to do, they are leading in some form by initiative.
   This was a misconception that i had at the beginning of the year. At first i believed that a leader was someone who held power, authority, and people looked up to them for advise. I now realize that each and everyone of us is a leader in our own way. I have learned that a leader is someone who takes initiative, or does something out of the ordinary for either people around them or for themselves which is self leadership.
