Practice Under Pressure

Impromptu speaking is a trainable skill, not a personality trait. Practice with a partner: have them throw random topics at you and respond using PREP within 30 seconds.

Sometimes you start answering and realize halfway through that you are lost. The recovery move is simple: stop, take a breath, and say "Let me put that more clearly." Then restart with PREP. Most audiences remember the clearer second version more than the stumble.
