Do you focus more on the ums and ahs of a speech than the content?  Perhaps you have fallen into the trap:

Just found a really interesting interview with David Brooks, the 1990 World Champion of Public Speaking, where he says:

There I was, one of the top nine speakers in all of Toastmasters in 1990, preparing for the World Championship. As I practiced my speech in front of speakers who had not attained such lofty credentials, one beginning Toastmaster wrote a comment in a post-speech evaluation. She simply wrote “I really liked when you said ‘You’re not supposed to know the Lone Ranger’s name.’” Well, when I read that note I instantly reacted defensively: “That’s not what I said.” But in a flash it hit me… “It’s not what I said, but it’s better!” I am grateful that I was smart enough and humble enough to acknowledge a better idea, without regard to the inexperience of the source. From that I learned “Keep your eyes and your ears and your mind open; you never know when a teacher will appear.”

Designing a presentation without an audience in mind is like writing a love letter and addressing it: To Whom It May Concern.
