Thanks for the comment.
It is not an obvious way to write. When we write, we want everything to come out perfectly and so we end up torturing ourselves writing a few words before throwing up our hands in frustration or finding something else that needs more urgent attention.
The whole idea is to just dump your ideas on the page – create your raw material – and then massage it into shape.
THe other problem is that writing and speaking seem so very similar and related – after all, we use the same words and structure. But … if you were to transcribe a normal conversation, you would find it is horrible writing. Conversely, good writing both (1) reads well and (2) is spoken well. One of the tips to see how your writing is, is to read it out loud. If it doesn’t sound good, then it is not good writing.

Hi. I guess writing succinct pieces counts as writing quickly 😉
