I don't know the point of the text before I start to write. I just sit on the chair in the front of my laptop and write without stops and pauses in English. I follow the single rule that sounds like "just don't stop" — and I get the text. It won't be a text of my dream — but I will have the option of editing of this after getting it done.
I just write without stops the whole text with mistakes from the beginning to the end. I don't worry about style and beauty of the text on the first stage, I will care about it after. I free the current of words from the head. When I complete the text, I can make as many checks and corrections as I wish.
