Is it possible to write a book if you're not into literature?

As far back as I can remember i have been working on this one story - that's two decades of creating and perfecting characters as old and real as myself - and i have always felt that the one thing i am destined to do with my life is write this one story. But the problem is, i don't really like literature. I used to really enjoy writing and was good at it but the past few years i just can't get myself to care about the way i write. I try to jot down bits every day but i have never been able to write a full chapter, in fact i rarely finish a full page. Maybe i am too concerned with telling the story, but the story is so big and has so many layers it's almost impossible to tackle it with words; when i think about my story it's more visual and emotional, like watching a movie. I dunno if this is making sense to anyone, but how can i approach writing this? I want to write it so badly, it's all i've ever wanted, i don't know why i can't!
