FEEDBACK - I thought the first tip was a great thing to think, wince most of the time we worry about the presentation itself instead. we never really give a eye to the audience and what they think and what they see. The next tip of building on ideas is a great way of structuring your presentation, since it allows you to give a presentation that would make sense and would be memorable. You wouldn't want to give a presentation that is memorable for the wrong reason.
          Using visuals lets you give a different way of showing information instead of explaining in a thousand words. It would better instead of making your audience sleep to your long speech. It's always good to summarize your presentation your presentation in simpler words or to have a story with it. You want to be able to give presentations that the listener would be able to understand and remember more easily.
