In fiction writing it is often the case that a character has a want, something that the character is aware that they desire to obtain or achieve and a need which is a psychological element that the character is usually unaware of that they require to become their better self.
Here are a couple of examples to illustrate my point. In JawsChief Brody wants to make his community safe, in particular to stop the shark attacks. His need is to overcome his terror of the water. He doesn’t go around in the story saying or even acting like this is a goal, but it is the character growth and evolution that makes the story satisfying. In Back to the Future Marty wants to ensure his parents meet so that he and his siblings will exist, but his need is to gain the self-confidence for his own artistic pursuits. (A need that was ignored the sequels.) Achieving his wants allows him to meet his needs.
It is important to have needs and wants cleanly separate goals. In the musical/fantasy Xanadu Sonny’s need and his want are precisely the same thing. He wants to be inspired to create original art and it is his psychological need as well. In addition to the film’s numerous flaws, this means that there can be no arc, no character growth for Sonny. If a character’s need is the same as their want, there is no change to the character when they achieve it. A static unchanging character is ultimately unsatisfying it is why the final shot in The Hunt for Red October is critical, only by seeing Jack asleep on a plane, having fully met his need to overcome his fear of flying can we appreciate his character’s growth and change.
When you create character to drive your stories think about their wants, the plot, and their needs, the story, are distinct things for fuller richer tales.
