In 'The Secret Life of Walter Mitty' we can find not only one message or phrase to describe his 'zoning out' periods (where he used to be in this imaginary situation), but I would choose: 'I just live by the ABC's: Adventurous, brave and creative. At the beginning of the movie, we can see a boring and dull character, with not a single anecdote to share, with no confidence to approach the woman of his life, and assuming a role of everyone stepping on him. But when daydreaming, Walter was not only another person, he was inspirational and brave, and turned always to be a kind of hero for others.
