"Well, I guess it's time for my root canal."

That was the most memorable thing that Ed would say to me all day. Ed (not his real name) was the number-two executive at a major U.S. financial firm, and first in line to succeed the soon-to-retire CEO. He had been through the wringer with a number of media trainers, and it showed.

We had been introduced, and Ed just didn't want to be with me. There was a seemingly permanent scowl on his beefy, reddish face. He had a perfectly pressed shirt and great gold cufflinks, but his collar was a couple of sizes too tight.

When it came time for our mock interview, Ed spoke to me in a laconic monotone, scattered with eminently quotable moments like: "yes," "no," and "I dunno, about six or seven people." It made me wonder how he had gotten as far as he did.
