Command and control. And nurture and inspire.
Unfortunately, agencies are usually lousy with the first kind and scarce on the second.
There isn't a creative working that hasn't felt the clumsy, heavy-handed thumbprints of an overbearing creative director on their work.
For some reason (cough "ego" cough "insecurity" cough cough "douchecentric personality disorder" cough), they feel the need to "make the work their own," agency code for "Just put my name on the award show entry form." and "I think I'll stay at the International Carlton at Cannes this year."
Having been a creative director, I always made it a point never to forget what it's like to present work. And being a copywriter, I never forget what goes into coming up with those ideas. So I always went the nurture and inspire route.
Here's the dirty secret about being a creative director: it's a lot easier than some of them make it look. The trick is to hire great people, make sure they don't run off the rails, clear the path by running interference for them, then get out of their way and let them do what you hired them to do.
Their success is your success. Bask in the glow. Repeat.
I'd like to suggest not only creative directors, but everyone in agencies—and in life for that matter—try to be more encouraging, supportive and inspiring to their colleagues. It's not a lot to ask, and it is the golden rule after all—or at least golden rule adjacent. Be the kind of person people want to work for - it's how you'll get the best work out of them.
After all, you've already got the job.
