If you’re a writer and someone pisses you off, or picks a fight (or the opposite, you pick the fight) or even makes you cry, welcome it. In fact, run for your notebook and write down how your body feels. Is your throat tight? Are you teeth clenched? What about your stomach? Does it feel liek someone punched a hole straight through you?
When conflict arises and you can bodily feel the surge of rage, despair, joy and lust, it is authentic. The situation may be total bullshit and unfair and then a year from now you’ll wonder exactly what it was that set you off. But if you channel the response into your work, which is different than a rant, it’s like compost and it will only make the story and the character much more vibrant.
