You’re just certain your resume is perfect — that it’s going to take you from business school to the boardroom; or from the boardroom to an even bigger boardroom—one with a bathroom and fancy faucets.

But if your resume is so solid, why aren’t you getting return phone calls about those job openings? Is your MBA not good enough?
