Along the lines of being oractical - be pragmatic rather than theoretical.  I love theory and abstraction, but it is those of us who can help people to quickly translate the theory and context of leadership into action that is successful and satisfying that will be in demand.

I'll add that I see technology, specifically tablet technology, as a real game changer in how we deliver great content that connects people to us and facilitates their engagement with what we share and teach.  It goes beyond social to a connection far more personal.  The iPad was a game changer and I think we have only just scratched the surface on just how much of a game changer it will be for those in our profession.  That's why I am now part of Polymash - this is exactly the kind of thing we are now doing.
