Ah, inner rage. It feels cathartic for a little while, especially when you're making complex but incredibly insightful points with lots of subpoints and bullets and footnotes. But after a while, the process blackens the mind. What would happen if you dealt with your anger beyond the silent borders of your brain? This doesn't necessarily require a confrontation with the object of your fury. It means figuring out why you're so angry with her (or him) and why you feel you can't bring it up.
Note: This directive applies even if the person you're yelling at is yourself.
