Satisfy the right AND the left brain

I'm reading Garr Reynolds's 'PresentationZen – Simple Ideas on
Presentation Design and Delivery'
. Garr has a blog on the topic, too.

Seth Godin's advice on p. 20-21 is a real takeaway:

Communication is about getting others to adopt your point of view, to
help them understand why you're excited (or sad, or optimistic or
whatever else you are.) (…)

Our brains have two sides. The
right side is emotional, musical and moody. The left side is focused on
dexterity, facts and hard data. When you show up to give a
presentation, people want to use both parts of their brain.

they use the right side to judge the way you talk, the way you dress
and your body language. Often, people come to a conclusion about your
presentation by the time you're on the second slide. After that, it's
often too late for your bullet points to do you much good. (…)

Communication is the transfer of emotion. (…)

If everyone in the room agreed with you, you wouldn't need to do a presentation, would you? (…)

[T]he reason we do presentations is to make a point, to sell one or more ideas.

you believe in your data, sell it. Make your point as hard as you can
and get what you came for. Your audience will thank you for it, because
deep down, we all want to be sold. (…)

First, make slides that reinforce your words, not repeat them. (…) No more than six words on a slide. EVER. (…)

don't use cheesy images. Use professional stock photo images. Talking
about pollution in Houston? (…) [W]hy not read me the stats but show
me a photo of a bunch of dead birds, some smog and even a diseased
lung? (…)

Third, no dissolves, spins or other transitions. Keep it simple.

create a written document. A leave-behind. Put in as many footnotes or
details as you like. Then, when you start your presentation, tell the
audience that you're going to give them all the details of your
presentation after it's over, and they don't have to write down
everything you say. (…)

Don't hand out printouts of your slides. They don't work without you there. (…)

put up a slide. It triggers an emotional reaction in the audience. They
sit up and want to know what you're going to say that fits in with that
image. Then, if you do it right, every time they think of what you
said, they'll see the image (and vice versa). (…)"
