What does positivity has to do with presentations? The answer is just one word: Everything. Positivity includes all the emotions associated with being nice — these are sincerity, genuineness, truthfulness, and trust. When you have an aura of these qualities around yourself — and your slides sync these qualities too, then you can be a better presenter even if you lack some of the other qualities associated with better presenting. These positive qualities are not the icing on the cake because they do not add decoration — rather positivity is the sugar you add to the cake itself.
