I have just read the articles at http://www.tuffledarskapstraning.se/bibliotek/ - all in Swedish - really good inspiration.
Makes me think of "When the best leader's work is done, the people say, 'We did it ourselves.'"
From http://blogs.hbr.org/goldsmith/2009/11/leadership_isnt_about_you.html I get the quote "Your team is more critical to the success of your project than you are." - which leads me back to Agile - "To succeed with Agile, Management's need for results must be greater than their need for control" quote from Israel Gat, formerly of BMC Software
