Humor heals the heckler.
Ask a heckler to identify himself and his company. They usually prefer to be anonymous.
I use many props. The props act as cue cards reminding me of what to say next.
The simplest way to customize is to phone members of the audience in advance and ask them what they expect from your session and why they expect it. Then use their quotes throughout your presentation.
They expect a professional presentation, so they expect to see a professional. Dress appropriately for the occasion, but don't be one of the crowd.
I never use notes, they interfere with me.
It takes one hour of preparation for each minute of presentation time.
A theme is a memory aid, it helps you through the presentation just as it also provides the thread of continuity for your audience.
There are always three speeches, for every one you actually gave. The one you practiced, the one you gave, and the one you wish you gave.
The audience only pays attention as long as you know where you are going.
No one can remember more than three points.
Ask yourself, If I had only sixty seconds on the stage, what would I absolutely have to say to get my message across.
