Leading - The Power of Why

This TedTalk is about 6 years old and many of you have probably seen it before; however, it is one of those talks that I go back to periodically and re-watch because of its powerful message.  It is absolutely worth the 18.5 minutes.  Please take some time to watch it.
I am generally very skeptical of relating to education, books or talks that are business oriented.  This is one of those talks that I connect with as an educator.  Simon Sinek lays out for us the power of "WHY?"  He demonstrates how leaders who are successful understand and use that power to their benefit while those who don't, fail or simply get by.
If you are in a position of leadership or aspire to be, I encourage you to think about why you do what you do and how you share those ideas, as opposed to focusing simply on what you want to do and how you want to do it.
I find this notion very powerful. What are your thoughts?
