When the great Phidias designed this temple to house goddess Athena Parthenos, I wonder if he realized that this rubble of a ruin would one day stand as a testament to the Athenian Golden Age and parade itself as the paragon of Western civilization. Perhaps not. Any here is why?
Nancy Duarte, the most sought after presentation expert says, 90% of the creative process is actually destructive. You create a slide presentation—and then slowly but surely see what you can peel away. What the mighty Phidias could not possibly achieve, disastrous geo-political affairs managed to turn the temple into a core shell of pristine elegance that seems to follow this destructive law.
When you are presenting at a trade show or an event try using using a single word on a slide to convey your core message. Want your audience to remember various benefits? Don not plaster all bullet-style on a single slide; Reveal them one at a time, unveil a mystery, create a story, and share an example or anecdote to illustrate each one. "Have an image or quote that accurately expresses your idea? Let it! "Don't be afraid to remove everything else from the slide, and let that one powerful image say it all."
The mathematical ratio "phi" is a tribute to the phenomenal Phidias. The sculptor of the goddess of wisdom have successfully spread his ideas & moved people over centuries.
Don't just share your ideas or your data; make meaning. Again in the words of Nancy Duarte, don't focus solely on changing minds; put some effort into changing hearts. Powerful imagery and though-provoking video are excellent tools for connecting your audience to your message emotionally—which is how we humans make decisions.
