Credibility: 15 Facets To Speaking Professionalism: #5 - Notes
Notes impact our credibility whether they are present or not. If you don't use them, and then forget your presentation, you're done for. If you do use them, you run the risk of using them incorrectly. Depending on the length or content of your talk, notes may simply be a necessary convention, unless you possess a photographic memory. If you are primarily telling stories and are not spitting out hard data, your lack of notes will work in your favor.
