A constant concern for many speakers is the use of notes in their presentation. Should I use notes? The answer is “depends.”
If your presentation is long and technical then the use of notes is imperative. During your talk you must present yourself as the expert. If your information is incorrect to any degree, it will impact your reputation as the “expert”. Or giving an incorrect quote can be detrimental. During this type of presentation your audience expects you to use notes. The complexity of your notes is not as important as being able to see and read your notes. It is imperative that your notes are easy to read and accessible. This also takes practice.
Trust your ability as the expert. Maybe all you need is a series of words in a large font to remind you of what you want to tell your audience. Large font makes words easier to see and does not restrict you to the close vicinity of the lectern.
