In the 15 minutes before you're about to give a big, important presentation, it's too late to change the content of your speech, says Darlene Price, president, of Well Said, Inc. and author of "Well Said! Presentations and Conversations That Get Results."

Building blocks such as analyzing the audience, creating well-designed slides, and rehearsing aloud should have already been laid, says Price. "Now, the big moment has arrived, and an eager audience awaits your message."

Whether you're stepping to the front of the room to speak to just a few people, or making a grand entrance in a ballroom to address thousands, you can effectively use the time immediately before you go up to prepare your body and mind for peak performance, Price says.

Here are 12 things you can do in the 15 minutes before a big presentation to optimize your speaking success:

1. Use the restroom. "First thing's first," Price says. "Needing the toilet when you wouldn't normally 'have to go' is a common reaction to anxiety and pre-speech jitters. Why take chances? Plan ahead and use the restroom in the moments prior to going on stage."

2. Check out the meeting room and audiovisual set-up. As the speaker, be sure you know the environment, including the seating arrangement, presentation electronics, microphone, and lighting. Get to the room early and ensure you're comfortable with the set-up. "This step shows the audience you're prepared and helps ensure your presentation runs smoothly," she says.

3. Meet and greet the audience before you speak. Shake hands and talk with as many people as possible ahead of time. "This shows the audience you're approachable and personable," Price explains. "You may even learn a few names, issues, and stories to weave into your presentation. Plus, having conversations with your listeners ahead of time transforms scary 'public' speaking into natural relaxed 'personal' speaking."

4. Listen to the speakers who go on before you. If you're not the first or only person presenting, it can be helpful to pay attention to what the people who go before you have to say. This way, you can get a sense of what ground has already been covered and what the audience's mood is like.

"If the energy in the room is low, you may need to incorporate elements to pick it up," public speaking expert Andrew Dlugan writes on his website , Six Minutes.
