You can learn a lot from joining Toasmasters and this is a video of a Toastmaster champion and I love it. You cannot hear his whols speech though and if you like it like I did, you will regret that the video stops. Because he uses a great skill which is : make the audience eager to want to listen to your message. And use silences to do that…
This is a rule that I love by Guy Kawasaki. He is a venture capitalist and hears lots and lots of pitches. His advice for a good presentation is the 10 20 30 rule : maximum 10 slides, speak maximum 20 minutes, and use a font (letter size) on your slides of minimal 30 !!
I was talking to some lawyers yesterday and was interested to learn that a good lawyer knows the first sentences of his plea by heart. this is exactly my advice for your presentation. I don’t learn my presentation by heart but I do know what my first sentences will be. For the rest I relie on the preparation I have done. I know my strcuture and I know the order of my slides. This gives me the confidence that I am on top of it. So please be an excellent lawyer and learn your first sentences. Before I go on stage I focus very much on the structure of the presentation, the big parts but some 2 minutes before I atually go on stage I focus very much on these first sentences.
