If you're allocated five minutes to present your thinking and insights, you can do one of two things. You can try to cram your regular half hour into the reduced time which involves subjecting your audience to a blur of slides and/or an avalanche of speed-reading.
Or you can acknowledge that five minutes is not thirty and tailor your presentation accordingly. Embrace the limitations that are set rather than see them as an inconvenience. You may not impart as much information, but at least it will be heard.
