When someone asks you what you do, do you freeze up or start stammering? You need a concise, memorable response prepared for all the times when you’re asked about your work. This is sometimes called your “elevator speech.” Why? Imagine stepping into an elevator with your biggest prospect. She turns to you and asks, “So, what exactly do you do?” You have 30 seconds—the time it takes for the elevator to get to her destination on the 25th floor—to describe yourself in such a way that she immediately understands why you are the solution to her problems.
