Screenwriting is a terrible way to make a living and I always try to talk anyone out of it. Until you sit in a story meeting with studio executives with no particular ability or actors who haven't even graduated high school telling you exactly how to change your script, you haven't experienced what it's really like to be a screenwriter in Hollywood. Also, unlike novelists and playwrights, you don't own the copyright on your original material. It hurts when you sell a project you love and then suddenly the project you really cared about will never see the light of day.
