Having been engaged to make a presentation in a conference, one challenge you will have to tackle is that of figuring out ways of making your presentation more impactful.
One way of making your conference presentation more impactful would entail undertaking a lot of research, to come up with truly valuable material for the presentation.
Another way of making your conference presentation more impactful would entail coming up with real life corroborations of whatever you say in it. If, for instance, it is a presentation on the ever emotive subject of government support for the poor, through community services and other similar initiatives, you can go to the ground, pick up real life stories of people who are in the system, and incorporate the said stories into your presentation. You will thus get a chance to create a strong impression on the conference attendees, and if nothing else, they will be better placed to remember the content of the presentation.
Yet another way of making your conference presentation more impactful would be by figuring out ways of making it more interactive. If nothing else, this will ensure that the attendees remain attentive throughout the presentation, which will in turn increase the chances of them benefiting from it in one way or another.
