My struggle with writing is I start out wanting to share an idea, but then I get caught up in the details and before long I'm writing and editing--or, realistically, procrastinating--a 2,000-word article that overshadows the main point.
Lately I've challenged myself to say just enough to express the idea, and nothing else. Maybe I'll write about the execution details later, but for now I just hope to get people thinking.
I am struggling as well with a similar problems and the more I am educated about it the better!
[edit] This would allow you to say just enough to get the point across, while still doing a deep enough dive on points that need more tactical information. [/edit]
