You've got it precisely... It's like counting to 10 while considering if high fiving someone in the face, with a chair, is the best course of action.

The best thought window I've created so far is for my bf... Whenever I felt the urge to push really hard and spew vitriol at him, I would spew it in my *****out boyfriend diary. I'd write and rewrite, sit on it and edit it for days. If something in there really needed to be said, I would be calm by the time I said it.

Haven't used the diary in over a year now, and no longer textually harass him.

Windows take a lot of practice, but the best method imo, is to step away, and in time, with practice, it becomes easier, more natural.
