Impromptu speaking can develop important skills like confidence, leadership, and communication. When speaking impromptu, take time to prepare by collecting thoughts and planning an opening, body, and conclusion. Remain confident by standing tall, maintaining eye contact, and speaking slowly and clearly. Focus on the subject while drawing from personal experiences, opinions, current events, or humor. Keep the speech brief and concise by being to the point without rambling. Practice impromptu techniques like PREP (Point, Reason, Example, Point) or Past-Present-Future to structure content on the fly. Preparing for common topics can help should the unexpected opportunity to speak arise.
