When you want to insert conflict into your stories, you're not limited to conflict between people, or between man or woman and nature. You can use internal conflict, which is, simply put, "a character's struggle against himself or herself." (NTC's DICTIONARY OF LITERARY TERMS.)
A good example of this is Holden Caulfield's internal conflict in CATCHER IN THE RYE.
