Presentation FAQ: Should I memorize what I have to say?

I came across a question on Quora today. What is better? Memorize your content and deliver your presentation OR read your notes.

My answer will be none.

You should not read out anything from your notes while delivering your presentation. At best, have a list of bullet points if you want not to forget anything and refer to this list once in a while.

You should not memorize your content as well. Memorizing is the worst thing one can do. Rehearse the presentation 5 to 10 times and you will naturally get into the flow. You will know what to speak when without memorizing anything. Hence the final presentation will come out natural.
