First of all, don’t overdo it. If it’s dry, it’s dry. I heard someone link his call to action to survival, which was a bit of an overstatement. Modesty in all things!
Nevertheless, since I often find myself urging clients to include emotional arguments as well as fact-based, here are a few tips.
- Reason makes us think. Emotions make us act. You need both.
- Begin with the problem that your audience faces.
- If they don’t face a problem, begin with the opportunity they have.
- Then talk about the consequences if they fail to take advantage of the opportunity.
- Personalize your message. Speak about your own experience. Disclose something about yourself. Confess your own struggle in regards to the issue, or a similar issue.
- Tell stories that are about life-changing experiences. Make sure your stories have a character, conflict, and dialogue.
- Stories about people they know, or famous people, living or dead, are most effective.
- Use emotional words. I once sat through 16 people delivering the exact same presentation, and the only person I could remember when it was over was the one who said, “I love my job.”
- Look your audience in the eye, one person at a time.
- Smile when appropriate. Visibly enjoy yourself.
- Don’t talk about how dry the topic is. Ignore the dryness, and find a way to make it moist.
The mother of the great American poet John Berryman told him, “Ever to admit you’re bored means you have no 
inner resources.”
Don’t let your topic bore you, or you’ll bore your audience. Find a way to fall in love with it.
