Here's why:
* Informal Tone: Short sentences mimic everyday conversation, which tends to be more direct and less structured.
* Easier to Understand: Shorter sentences are easier to digest, making your speech more accessible and engaging.
* Increased Pace: A rapid succession of shorter sentences can create a sense of urgency and excitement, making your speech more dynamic.
* Emphasis: You can use a short sentence to emphasize a key point or create a dramatic pause for impact.
However, don't go overboard! A speech should still have a natural flow and coherence. Mix up sentence lengths to keep it engaging and maintain a good balance.
