Thanks for weighing in here and for sharing your post on the subject.

I am a big fan of the practice of inventing your own definition of leadership.  even if we end up adopting some or all of someone else's words, in the process of the inquiry our understanding of leadership is enriched.  I pulled the definition you offer in your post and share it here as a great example of this:

"Our definition of a true leader is:

Someone who is responsible for or oversees of a group of people, who has the ability to inspire others to achieve tasks and goals they might not have otherwise been capable of reaching, and who can create positive change in a situation."

What is particularly interesting to me is that you used the adjective "true" in front of leadership.  Adjectives are used more and more when the word leadership is used.  Perhaps that is because the more we inquire into leadership the more we realize it is not a "one size fits all concept".  I would be curious to know why you chose to add the word "true".
