Writing is hard. Especially if you start thinking. Never stop to think about what to write (unless you must), it will ruin the flow. Never stop to correct yourself, to judge or run a spellcheck. Don’t do that; that’s what editing is for.
I don’t think so. Rewriting and framing the context is hard if you don’t consider those at the outset. I have been writing consistently for over 5 years, and use the blog for several feeder ideas. The trick is to understand the requirements and use the source to turn into blog posts. Searching for the relevant write ups is challenging to dig through. Therefore, I have some familiar methods and resources to track and link them here.
A small essay (that is linked here) and a worthy read.
