haha i remember in high school i would have to memorize my script word for word to prevent verbal vomit and actually be considered a presentation i was actually known as “one of the good ones” for presentations cause i would practice the hell out of them time every paragraph mark down every pause point highlight sections that need more enthusiasm etc it seemed quite excessive from the outside but it was so i didn’t embarrass myself in front of the class by losing my train of thought and turning as red as a tomato while the timer still ran   my friend convinced me that it’s easy to improv presentations if you know the content and as the easily convinced person i am i did it and i fucking failed it so yeah if something works for you stick to it if it aint broke dont overhaul and fix it
