Speak about things you know really well and fully understand. For any speech you plan to give, you should know much more about the subject than you can explain in the given speech time. Narrow down your speech to a very small bit of what you know, focusing on clearly and efficiently getting across each of the few points you want your audience to fully understand.
Narrowing,
