10, 25, 45

I’m very interested in public speaking. I enjoy doing it and I enjoy listening to a great speaker. It’s a wonderful, even essential skill to develop for anyone who wants to have more influence, for those who wish to lead.

To that end, for those aspiring to increase their influence through public speaking, I’d like to suggest that you develop three talks of differing lengths; 10, 25 and 45 minutes.

Your 10-minute talk is one big idea supported by one story.

Your 25-minute talk is one big idea supported by two stories.

Your 45-minute talk is one big idea supported by two stories plus 5-7 minutes of audience conversation about how they feel about what you’ve been saying (because no one wants to sit for 45 minutes without a chance to talk…about themselves) and 5-7 more minutes devoted to their sharing of what they just said.

Two takeaways: first, you deliver one big idea, and only one big idea. Second, your talk isn’t about you, it’s about them. The longer you have to speak the more space you should create for your audience to do so.
