In order to make choices about actions and identify acting objectives, actors divide the script into units (called “beats”).
Business speakers should do the same. Take a deep dive into the notes for your presentation and divide it into beats. Each beat is a separate topic, smaller than the overall subject of the message (not what you are doing with your words, but what you are talking about).
In the margin of your notes, label each beat: a simple noun or noun phrase.
When you know what each beat is about, you will be ready for the next step: identifying an acting objective for each beat.
