Public Speaking

My sister told me about a conference scheduled for November here in Dallas and encouraged me to submit a proposal. I’m not afraid of public speaking, but rather others understanding me and hearing their questions.
A few years ago, I did a panel at sxsw and it went OK. I was the moderator, so I didn’t have to worry too much about interacting with the audience and panel members. But I think I’ll pass on any future panels — unless it’s people I’ve met in person and understand.
For this presentation, I plan to bring index cards so the audience can write questions. I haven’t decided whether I’m going to collect the questions or walk around and read them while letting the person read the question out loud. I did this once in college when I did a lesson plan with children (we all did short lesson plans). Barely can remember how it turned out, but it must’ve been fine as I would remember it if I struggled or ran into problems.
The hardest part isn’t speaking and listening, but creating a creative presentation instead of falling into the PowerPoint Trap. I plan to dig into Metaphorically Selling for some ideas.
