I have never had to do a presentation—yes, I am that lucky. Yet, if I ever needed to do one, I would opt for the Takahashi Method.
“Unlike a typical presentation, no pictures and no charts are used. Only a few words are printed on each slide—often only one or two short words, using very large characters. To make up for this, a presenter will use many more slides than in a traditional presentation, each slide being shown for a much shorter duration.”
