Yes, many of us just freeze when we're talking in front of people. We'll be thinking one thing or saying another. We'll just freeze. This is one of those moments where the audience doesn't know what to do. Whether to clap and show you support, whether to panic and wonder if something's wrong, or whether to collectively hold their breath in awe of what you'll say next. But you don't want to put your audience on edge like this. You saw in Barack Obama's acceptance speech at the DNC how fluidly he transitioned into each point, and how the crowd reacted. You wanna have your stuff together when in front of any group of people, or else they will suspect something is wrong. You can address this problem by stuttering less, taking "Ah's" and "Umm's" out of your speech, and being more conversationally fluid. Then, the next time you have a CEO address, or even a shareholder meeting, you will knock your proposal out of the park
