Trying to read the creative director’s mind may be the thing that’s holding you back. The truth may be that your fearless leader has no idea what to do, which is why you’re being hauled in to help solve the problem. Do what you think is right, then present it. The discussion around your efforts may help focus the search.
Most creative directors are just like clients: they know it when they see it. Lay out some options. Trying to use ESP can paralyze your thinking. Follow the input, and your heart, and go make the work you think is right.
