Performance under extreme pressure is by definition what sorts out he great from the average in other disciplines: sports, music, performing etc.

If you haven't experienced sport (or similar) at the highest levels you probably won't get how much a few insane minutes can enhance your mastery. It really is a whole new level, where everyone is competing at their peak and you have to greatly improve your level or fail miserably.

This type of pressure & competitiveness just doesn't happen in most business environments, so the degree of pressure to lift your game isn't there.
