If you are preparing to deliver a presentation that matters (to you), consider the following.
Start with the audience and the change you’d like to see (even when you are just presenting results, you are still demanding a change). List them down somewhere and have them visible throughout the process.
Have the deck ready early, at least a week before the presentation.
Little text on a slide is always better than more. Always.
A list is a list even without a bullet.
Allow enough time to collect and implement the needed feedback. If you get feedback too close to the time you are supposed to deliver the presentation (<24hrs), be brave and disregard it.
Write a script for the key points and the transition between slides.
Rehearse the presentation multiple times, keeping the script at hand, but without reading it.
Few hours before the actual delivery, free your mind and take a break from the presentation. Do something else. The deck is ready by now, and so you are.
