in the secret life of walter mitty, the main character leads a dull life, or so he thinks.in all his daydreams he plays the role of some hero or a man who is unbelievably resourceful.whether a pilot, a surgeon   or even a criminal, he is better, so much better than all the rest of the characters in his delusions.he comes up with ideas nobody else could have conceived .when he comes back to reality, whatever he has to deal with seems silly, boring without any motivation to deliver.
