In fact, you'll find that the best structures for presenting your ideas are three-part structures.
Most people think that knowing what to say is the hard part of presenting.
Instead, it's knowing what to leave out - and delivering a succinct, coherent message. Trying to deliver too much information will freeze your mind, tie your tongue, and confuse your listeners. It's great to let feeling into your presentation, but emotion persuades only when it's contained within a clear, sensible framework of ideas. If you use too many notes, or read them verbatim, you will lose your listener's attention. A simple three-part structure keeps you logical and easy to follow, but it also allows you to fill in the details in a spontaneous, natural way.
