Metaphor is a great guide.
- in quotes;
- in images;
- in visuals.
By using it, one can easily incorporate stories and images into a speech, so that it sounds perfectly clear and natural. At the same time, metaphors also is used to put an impressive end to a speech.
The main thing is not to overdo with it, just as not to introduce any new topics when finalizing your narrative. This can dilute the focus, distract or even confuse.
It is also helpful to use a verbal or visual metaphor that has already been mentioned in the presentation, so that the last slide will summarize the speech and give you an opportunity to "quit" through a revealing image.Let's say the main part of your presentation was dedicated to the virtual assistant called Keanu, then it would be nice to insert a picture of him with a motivational phrase at the end.
