This is session 3 of the Awesome Presentations Workshop. You can watch the video for session 2 (developing the story) at https://www.youtube.com/watch?v=jC1glujAhZI
The purpose of a slide is to illustrate an important point in the story. Without a clear story it's impossible to create an effective slide. Once you know what you want to say, notice all the things in your slide and ask why.
