How do I begin to write a novel?

help me /book/, you are my only hope

Last night in the shower I had an idea for a science fiction novel with religious overtones. I can fill you in on the details of my idea later, but that's not really important. My question is: what are the online resources or books that a noob at writing should look at?

I know I am fairly decent at writing academic essays, but writing fiction is an entirely different story. As a young teen I tried "writing" one or two novels, but failed miserably, especially on the dialogue. How can I improve myself, /book/?

as a writer, I want to read something I admire for the writing
You shouldn't be reading as a writer. You should always be reading as a reader, or else poor bastard, you.

As for writing what you want to write instead of what you want to read, I'll let you in on a secret. This is the sole reason for "writer's block" happening. "Writer's block" doesn't even exist, it's just because writer is interested in _finishing_ the product and not in the _finished product_, so he instinctually wants to stop working already, because it's his natural goal.

I repeat.
1. Writing what you want to write is wanting to FINISH THE PRODUCT, essentially. This naturally leads to the stupidly termed "writer's block".
2. Writing what you want to read is being INTERESTED IN THE END PRODUCT ITSELF, which is the only psychologically natural way to fully realise your potential without any subconscious roadblocks like "I can't [read, don't want to] write".
