One of the problems with using the same templates repeatedly is that you risk boring your audience. When giving any type of presentation, you want to draw your listeners in to what you are saying. Boring props and overused PowerPoint templates are a sure way to turn your audience off to your message.
In fact, many of the templates that ship with PowerPoint are too generic to be used for a specific presentation. Their abstract shapes and gradient colors are repetitive and boring. In many situations, several presentations are delivered back to back.
If you use the same old templates that ship with PowerPoint, you risk using one that was used before you. Psychologically, your audience will associate you presentation with the one that previously used the same PowerPoint template. If you want to stand out from the other presentations, make sure your template has a unique look and style.
That alone can disassociate your message from others. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
