Tips for presenters

1. Don’t memorize your presentation. Make brief notes to guide you.
2. Practice many times.
3. Relax, take a deep breath, and wait until the audience is quiet.
4. Speak loudly and clear, and use your voice for stress and emphasis.
5. Make eye contact with the audience as you speak.
6. Use gestures to show meaning. Make them slowly and clearly.
7.  Use simple visual aids that everyone can see.
8.  Don’t say, "Finished." or "That's all." Smile and say "Thank You".
9.  Think about how you can do better next time.

I think the two most important tips are '5- Make eye contact with the audience as you speak', and '8- Don't say, "Finished." or "That's all." Smile and say "Thank You".'.
