C) confident and heroic
In "The Secret Life of Walter Mitty" by James Thurber, Walter Mitty fantasizes about being a hero in a variety of dramatic and adventurous situations which differ greatly from his ordinary and rather dull real life. These daydreams portray him as confident and heroic, as he imagines himself as a skilled surgeon, a daring pilot, and a sharpshooter, among other roles, all of which require a level of confidence and heroism.
