Changing the Approach to Writing Posts

I alluded to making this post in my June Journal entry. About how I run things here. Specifically for this post — how I run through the act of constructing a post. I feel that there are some improvements I can make in this area, and I hoped to also get some input on this from you all.
How I do it at the Moment
Getting Started…

Ideas can come from anywhere. Random thoughts. News pieces. Game happenings. Other bloggers, via conversation or their blog posts I’d like to comment on or otherwise respond to at length.
When I can, I’ll construct a draft post — generally containing just a title to prompt memory of the idea later. Very rarely I might include some bullet points of things I want to cover in the post.
Sometime after the initial ideation, magic happens. But — and this is important — the magic can only happen while I’m not at a computer. While driving, say. The post will fully form, crystalise even, in my mind — a near masterwork of engaging writing and compelling argument.
Later, back at the computer with time to write the post — I’ll start tapping away, hacking together a far lesser version of itself. Not the best post in the world, merely a tribute. ;)
Putting the Post Together
During the process of failing to translate what once seemed a perfectly clear and constructed post in my mind to actual written word, I’m prone to distractions in all forms. I don’t think that’s the cause of the translation issue, but it certainly doesn’t help either.
The main distraction comes in the form of working on the post layout while writing the first draft. By which I mean I will insert images, format them, and if I need to jump into a game to get the screenshot I want — I’ll even do that.
I’ll eventually wind up with a completed post, which I’ve put together piecemeal. Editing as I go. A final review (often far more cursory than it probably should be) and then an instant publish.
I’m not very good with being patient and scheduling posts. Once done — it needs to go right then!
The Next Experiment
What I feel I should do instead — and will be experimenting with — is getting out a full, complete draft before doing any of that. Consider that first go in the same vein as a NaNoWriMo writing sprint. If you’re unfamiliar with the concept of a NaNo writing sprint — basically you write at speed for a set period of time. You completely shut down the inner-editor for the duration. Corrections of anything beyond a typo should be considered forbidden.
After the sprint is over you may consider your review process. Be that a rewrite or some intensive editing.
At first I thought my success metric was around time taken to write a post. This experiment was initially about reducing context switching between writing and formatting.
I actually don’t know that this approach is going to save me any time but perhaps it’ll result in a better quality of post with a rewrite/intensive edit phase put in. A harder metric to track meaningfully perhaps, so I’ll have to use my own satisfaction with a post when ‘done’ as a proxy.
But already I can tell making this change is going to take some very sustained and conscious effort. Cos uh… I’ll start with the next post? I did this one my ‘normal’ way. Hmm.
Anywho — as I said at the start, super curious how other bloggers out there go about constructing their own posts, and if there are any things that seem to work for you, or anything that you might consider changing. :)
