Embellish your points with story and examples. Structure your information. You and your audience will remember your points better if you have a clear outline. If your presentation involves statistics and analytical data, put them in a handout that the audience can refer to. Don't bore them by reciting a plethora of numbers.
Stories are what make a talk memorable and lively.
Don't read your speech. Look your audience in the eye. Write down key points or statements so you can refer to them, but deliver the rest of it spontaneously making eye contact. Practice with a tape recorder or in front of friends and family. If no one does, omit it.
