I write but never reread. The act of writing helps me organize my thoughts. Maybe I'll reread the last page when coming back to something but that's it.

So my advice is to write when you have a lot on your mind so that you can get it out of your mind. That's it.

Don't mess around with forums. That's for a different problem.

Keep a pen and paper handy always. There can be no barrier to entry or it breaks the flow.
