Most of the evil in the world originates from ignorance and narrow-mindedness. Be broad in your thoughts, be accepting. Be like the reed at the water's edge, bend with the winds, be sensitive to the world, but never let the bums break you. As a writer, you can write anything, as long as you clarify and fully understand the rules of the world that you create. In real life, the rules are already set, but the more fully you understand them, the better chance you have of bending, shaping and altering them to fit your own needs.
Life is hard.
Sometimes things don't go your way. Don't pull a Menendez and blow away your parents. Let it go, Eric. Move on, Lyle. Start a new project.
