Stories aren't a distraction from your points, they are vehicles that carry your point along and plant it firmly in your audience's memory. Long after you've forgotten the 57 bullet points someone tries to drill into your head, you'll still remember the points that were illustrated with a good story.

Spend some time with your material and try to find a story that arises out of it. Where were you when you first heard this idea? Who told you? How has this tactic affected your personal life? How can you relate it to your childhood...or your children?

Try not to be the hero of your own story. We will have trouble relating to you if you're a genius and have always been a genius. Talk about your own failures and faults. So if your talk is about overcoming procrastination for instance, you might tell a story about how you were in college and how many times you struggled with grades because you put off studying.
