David, did you ever read Julia Cameron’s The Artist’s Way? One of its tactics is the “morning pages.” First thing every morning while slurping your coffee fill three pages in your journal with whatever comes up, be it dialogue, free association, whatever. No self-judging. No editing out. Takes about 20 minutes, gets the BS over with, clears the mind for the real work session ahead. Sounds like that might be the place for anger. Should the energy of that anger adrenalize your words, great. You’ll be able to see what you said with a cool head.
