I love it. It's true. Absolutely true.
But if you're a young creative with aspirations of becoming a creative director, don't just jump to the right-hand column. Embrace the left side. Be about your book. Have lots of ideas. Worry about now. It's what you need to do now.
Someday, you'll realize you're more concerned about the client than your book. You'll know what finding the idea feels like. Unifying won't sound so lame and kumbaya-ish.
Nothing wrong with either column. Just know where you fall. And play your part as best you can.
