I was listening to the radio a couple of nights ago and heard Bev Brock speaking of Peter Brock, or Peter Perfect as he was known. She was explaining that what she believed made him “perfect” in the car racing world for many years was that he would imagine the whole racetrack, the whole race and the finish line the night prior to the race. “He was at one with the road in his prime racing years” were her words. Leading up to the race he was calm and focused.
Of course he had a team of people around him who new exactly what to do and who knew of his need to stay focused with no distractions. They were the buffer between him and any unwanted interruptions. You may not have a team around you before to step up to present, however you can imagine, or visualise if you like, the whole presentation right through to completion. You can visualise the room, the audience, how you are standing, how you are moving your hands and body. Visualise how you are interacting with the audience and prepare for questions that might be asked of you and how you will answer them. During this time you will require a quiet place with no interruptions. Take a walk or sit quietly in a favorite chair or room. Remember you are in control. You can choose to walk away if there are interruptions so you have the space you must have.
Do whatever it takes to achieve the mindset that will support you and in turn have you supporting your audience.
