Your slide looks something like this.
For a brief moment, you step back, take your investment banking hat off and take a fresh look at the slide. You can hear the voice of your mentor saying “remember that our clients aren’t bankers and you must always put yourself in their shoes whenever you present to them. See the pitch the way they would see it.” You decide to put your client hat on and take a fresh look at the slide.
You put your i-banker hat on again and pack up the books and think you yourself: “Heh, aint no way these Company A guys are going to see through this. If they were so smart, they’d be i-bankers.”
