Why do you do what you do?

Yesterday, in the rant inspired post, I mentioned a guy named Simon Sinek.  Here he is a few years ago with a TED Talk explaining his "Golden Circle" concept.  If you figure out why you are doing what you do, then alot of other things become clear.  That's how you lead something new... like a small business or other cause.  How did Simon come up with this concept?  It's in the short, five minute, video below.  Simon Sinek will change the way you look at things.  That's why he does what he does.
