Only the writer really knows the answer to that question. I start teaching a new class in a couple of weeks and in the first class, I often ask students their reason for wanting to write. Their answers vary, often having to do with their age or their chosen career or business endeavor.

I really like this quote by Nicole Krauss

Why does one begin to write? Because she feels misunderstood, I guess. Because it never comes out clearly enough when she tries to speak. Because she wants to rephrase the world, to take it in and give it back again differently, so that everything is used and nothing is lost. Because it’s something to do to pass the time until she is old enough to experience the things she writes about. 

Why do you write or want to write? Here’s a link to an article that explains a myriad of reasons people. I found it an interesting read.
