1. Use less distracting hand gestures
I unnecessarily wave my hands around too much, which might distract my audience.
2. Come up with a better, more engaging script
To be honest, I hardly ever actually come up with what to say and I just speak off-the-cuff. I should practice more and come up with a fun, yet impactful script.
3. Understand the topic better
Sometimes, I don't fully understand what I am presenting, especially in group presentations. If I don't know what I'm talking about, how would I expect the audience to?
