People should write when they are angry. Most clever ideas surface during moments of despair. Every piece of writing involves some sort of conflict. Instead of breaking things when you are angry, sit down and write an essay, a poem, a screenplay or even a book. Write a story; share the pain you feel inside.
More than likely, your stories will resonate with energy, a realness that inspires others to notice that anger only last momentarily. However, conflict has the ability to spice up stories. No life if perfect. People will hide their pain. If people want to inspire people, it is suggested that writing is best done during moments of anger.
