I landed on the topic I chose because I hold it very close in my heart. This is a personal experience I have, but very informational. To anticipate speech topics for future presentations I will probably create a list of things that are either currently on my mind, or that are occurring in the world today. Coming up with topics can sometimes be challenging, but as long as you research and have a known sense of what you will be talking about, your speech will be great.
I think it's a really good idea focusing your speech on something more modern or recent, I think that would keep a lot of peoples attention.
