Bill, love this freak'n post!  :)

You are so right, experience matters.  It's so important that we do our due diligence when letting someone in our ear.

I really resonated with the point about comfort/discomfort.  In leadership, as in life, the more comfortable you can become with discomfort the better off you will be able to lead others, AND yourself.

Great questions at the end to allow people to check themselves, as to whether leadership is something they are up for.

Great job, all around.  Thank you.
