I mean, every time I sit down at my computer or in that soft, comfy chair with a notebook I draw a blank! Then, the minute I stand up and start cleaning, an idea of brilliant strikes. I rush back to said chair and BLAM! I'm hit with the wall of white: that white page or screen that stares at you, taunts you, sneers at you.
Off to classes I go and I'm forced to write: short stories, memoirs, reviews, reports. They roll off my fingers and I'm actually proud of them. They're good enough to get A's which, right now, is all I can ask.
A few minutes of blissful nothing and I creep up on my notebook and start jotting. There! I'm caught! My mind shrivels up like a raisin and I'm left with gasping for the right word to at least end the paragraph so I'll be able to come back tomorrow (later?) and pick up where I left off.
You should be writing because it's what you eat, drink, breathe, live. Every waking moment of the day is consumed by story, YOUR story. It haunts your mind as you work, play, eat, sleep. And yet, when faced with the prospect of a blank page or hour with which there's nothing else to do but write, you're frightened away at the monumental task of creating a world.
You SHOULD be writing because that world is yours to create. Don't look at the novel as a whole but in sections. Take it a scene, a page, a word at a time. And don't beat yourself up if all you can eek out is one sentence. Let that one sentence come and trust that another will follow. And another. And another. A novel is evidence that the writer didn't quit. There is no one out there telling you it MUST be finished by such-and-such a time...unless of course you have an agent (or a professor) and in that case, chop-chop! Get the words out, the world on paper. Then, and only then, worry about form and function.
YOU should be WRITING. Why? Because it's who you are, what you are, what you want.
