Great question. Writing for me vs. publishing what I write are very different. I write almost daily by journaling. I have several journals as well. Some journal entries could be considered an article, although more loosely written at times. Some may be a short story seeking the inner self as well as poems discovering feelings in flux, conflict, or celebration.
At work I kept a journal on the desk PC and wrote short paragraphs all the time password protected of course. That was a problem solving technique and also used for venting. Sometimes too much is flowing through the mind and concentration diminishes resulting with a blurred focus. Writing it out and expressing both feelings and emotions for the moment allows the hazy fog to lift as a clearer path is discovered.
I giggle because it could be a one liner like "I do not want to do such and such . . ." over and over until ending it with "why?" Then, expanding on why both good reason not to do such and such may arise as well as an alternative solution. The real what, where, when, why, who, how and how much for such and such is brought forth offering opportunity(s) and too good cause for doing such and such. The whole writing process may only take five minutes, yet offer a much more peaceful day of resolve.
Then, there is writing for publishing . . .
