I used to think that business theatrics was the part in a pitch where you beg, plead and grovel. Turns out, business theatrics is a more accentuated way of presenting. Bigger voice. Broader gestures. Strong posture. Broad smile. Dramatic pauses. Keep your eyes glued on the audience. Business theatrics adds energy and confidence to what you have to say.
A good pitch must always have an element of show business.
