You may be surprised to learn that, with rare exceptions, your public speaking audience is rooting for you. Every time you step up to speak, they want you to succeed.

If you've ever witnessed a comedian bomb or a singer hit a "pitchy" note, you'll know exactly what I mean. The audience shudders with embarrassment for the performer. They want the person on stage to be successfully entertaining - that's why they came.

The same holds true for a public speaker. Your audience wants you to succeed, even if for no other reason than feeling that your presentation was a good use of their time.

To make them proud that they came, you must "own the room." Sound like a tall order? I'll let you in on four secrets for creating a presence that radiates ownership the next time you step up to speak.

Rehearse for public speaking. Most of the time, what we write doesn't translate well to the spoken word - and you won't know that until you hear it. By rehearsing, you'll lessen the chance of stumbling on tricky language.

It takes an average of three to five rehearsals to really nail your presentation. The first two will give you the chance to rework and refine your message, leaving you the remaining sessions to polish your pacing and timing. Final rehearsals should include any media that will support your presentation, and if at all possible, should take place in the actual location where you'll be presenting. Plan for at least three rehearsals so you don't run out of time.

Do Your Advance Work. Arrive early enough to walk around the presentation room, making sure it is set up the way you want. If something isn't the way you need it to be -an extra table for handouts, for example - you'll have time to get it fixed or implement "Plan B."

Advance work helps you establish a comfort level, helping you feel more in control and able to visualize your public speaking engagement successfully unfold.

Transform the Room. Unlike the two secrets above, this one is purely mental in nature. Close your eyes for a moment and shift your thinking. This is no longer a ballroom, or a boardroom, or a trade show hall...it's your living room. And the audience, each and every one of them, is a welcomed guest.

Just as you would greet guests arriving at your home, adopt the same attitude in welcoming listeners to your presentation. This simple change of perspective allows you to project confidence and manage the dynamics of the room. Because, after all, you're the host.

Develop a Ritual. Similar to many professional athletes, experienced speakers often perform a "pre-game" ritual to get themselves into performance mode before a public speaking engagement. What can you do to mentally prepare yourself prior to stepping on stage? It can be as simple as introducing yourself to a handful of audience members so you feel as if you're talking to people you know.

My own ritual includes greeting people as they arrive, taking a few minutes to myself just prior to the start of the presentation, then intently listening to the introduction so I am ready to walk briskly and enthusiastically to the stage. Once I arrive, I turn to look at the audience for a moment, pause, and greet them as I would welcome someone into my home.
