Nice article from Phil Waknell about making better presentations.
It’s all about context + audience (expectations).
There is no one-size-fits-all recipe, no magic formula here.
But, adding something personal makes always the difference between different presentation deliveries.
And the goal of a speech should always be about transforming the audience, making some change to them, having an impact, like a good story can does most of the time.
