This post seems to be more about writing in general. The first step in all writing is writing. Just get something down. Brainstorm. Even if I write something on a computer, if I want it to be good I print out my first draft double or even triple-spaced. The I revise with a pencil in hand, far away from my computer. That's when the real work happens.
Truman Capote had that legendary dis of Jack Kerouac ("this isn't writing it's typing!"), and even controlling for his bitchiness he was absolutely correct. I feel like we loose an important creative moment in not putting pen to paper at some point in the process. Writing long-hand involves a very different skill-set than tapping. Word processing makes writing too easy and this has had a negative impact on the quality of writing: words difficult to produce are necessarily well-chosen ones.
