I have a bit of a weird workflow to most things, especially when it comes to writing. When I have an idea for example, I like to ramble and add all the details that come to my mind in a free flowing kind of way, which usually results in a huge wall of text. Then later, I take a look at this wall of text and cut it down, usually by making a mind map of it, removing all of the unnecessary rambly bits, cleaning it up and making it easier to understand and follow. Out of all the things I wrote in that wall of text, only about 10% of the content survives the purge.
Is there a word for this kind of "destructive" way of working?
