Many stories from fairtytales to movie scripts are based on the idea of the ‘hero’s journey’ – there is a call to action and to leave the daily routine, which the hero is challenged to respond to. Think Gandalf arriving at the home of Bilbo Baggins – which kicks off the story of ‘The Hobbit’, taking Bilbo on a perilous journey into adventure, and out of a comfortable life in the Shires.
