I tend to speak quickly, so I end up being finished way faster than I should be... so on all my note cards, it says SLOW DOWN really big across the top of each card.
If you twitch, speak quickly, or have other characteristics about yourself that you're aware of, put them on your note cards so you're mindful of them. Just make sure when you practice you never actually verbalize those little self-cues, or you may accidentally end up actually SAYING them out loud when it comes time to present the material.
