In one sense you&#x27;re practicing the wrong thing. You need to practice going off from the top of your head, not practice any particular routine or speech. How long can you talk to yourself without going blank on what to say next, or getting stuck in a repetition loop? If you have this down, then you can practice speeches, but when you inevitably forget something because memory isn&#x27;t perfect, your skills at improvising and filling in the blanks and shifting topics will save you. Watch one of John Carmack&#x27;s talks. He just stands for three hours talking. No slides, no notecards. Sure he goes over notes and ideas for what he wants to talk about beforehand, but he doesn&#x27;t memorize his talk. That&#x27;d take way too long.
