“The best defense is a good offense” is an adage used in chess, sports, and military combat. It also applies in business. There are plenty of “high-stakes” moments in which people catch you off guard and make you feel defensive, whether by their choice of words or demeanor. A difficult client interrupts your pitch with a volley of unreasonable questions, a board member interrogates your investment case to the nth degree, or the boss dismisses your work on an important assignment out-of-hand.
