Memorizing a Business Presentation?

Hello. I’m new to the site/forums, also new to memory techniques. I read the book Moonwalking With Einstein and really enjoyed it, which is what prompted me to look further into mnemonics.

That being said, my interest is to use it for further my professional life. I give frequent sales presentations, for example I might give a short presentation for 10 minutes using powerpoint as well for visuals. Can someone explain or point me in the right direction of what method would be best for memorizing a presentation like this?

Thanks!

You could create a mindmap of your presentation and memorize the topics and subtopics of your presentation using the Journey Method, if you want to memorize numbers or text word for word you can use the PAO method: PAO
