Simon Sinek did a small session during Catalyst 2012 as he explored the idea what it means to use inspiration to lead people.  As leaders you can either manipulate people into following you, buying your product, or attending your event or you can inspire people.  Manipulation works; eventually, if you price a product low enough people will use it because it's cheap.  But manipulation does not breed loyalty or trust.  What if instead of manipulation we used inspiration?  Simon gave a similar talk at TED that I highly recommend watching to understand what he talked about.
