What tricks do you use to get past those parts you have no interest in writing whatsoever? Or to get started at all? Is it sheer force of will and discipline or do you have something you use to get you going?
I'm generally stuck with willpower, which is not my greatest asset by far.
Personally, I have this about once a day. Today, starting my next chapter loomed up at me and my brain cowered in a corner.
So... ....I played Papa's Pizzeria on Kongregate.
I am a professional procrastinator. I wake up with all the best intentions and then I avoid those intentions until they start talking sense. I live with the acknowledgement that I will write today, but it'll be when I'm ready to, not when I'm forcing myself to.
I do force myself to some days. But that's a different kettle of fish, I'm forcing myself to think of other, smaller projects when I really want to be focused on just the one.
Fact of the matter. If you really want to write, if you love writing more than anything on earth and a life without writing is meaningless to you (Over exaggeration used as point making device) then you will write. The same way a singer will always sing and a dancer will always dance. It's kinda in the blood.
I stop writing for a second and turn on music. Very specific music, mind you. I know that I want to get to point A to point B, but have no way of getting there. I listen to a song that conveys that gap, the start of the song representing A and the end B, and picture a story in my head. I use the story of what I have already written and move on, usually getting short scenes of a character running, fighting, talking, or something else. After that, I have a clearer picture of where I want to go.
When I find myself getting bored with my writing, it's because I'm tired or because what I'm writing is boring. If it's the latter, I rethink the scene. Why are my characters here? What's the point that the reader really needs before I move on? How can I facilitate communicating this as quickly as possible? Could I communicate it in an entirely different way? Is this scene really necessary in the first place?
If you're finding something boring to write, do you think people will want to read it? If it doesn't turn you on, don't expect it to push anyone else's buttons.
If it's the first draft of something, go ahead and put a note in the draft of what you're looking to write (I just put stuff in brackets). Just a sentence or two. Skip ahead, and come back to it later.
