How do I avoid distractions with my hands when making a speech so they don't look unprofessional? Well, for starters, don't do this. But chances are you're not doing this. So many people worry about oh, my hands will float around like Will Ferrell. The biggest thing you can do that will look distracting when you're giving a presentation is to hold your hands down or hold a pen to try to freeze your hands to look professional. Stop doing that. You want to move naturally. That's what's going to make you look comfortable, confident, and relaxed. So stop trying to freeze yourself or doing things like this. That just looks weird.
