Second off, it's about storytelling. Whether you're an art director or copywriter or just a writer, you need to know how to tell a good story - whether it turns into a TV script, radio script, banner ad or manifesto, your job is to weave wonderful stories.
This article is chock full of tips, advice and ideas to help make your stories better.
Now get to work.
