Practice makes perfect
“Four days ahead of the event you should spend 10 minutes practising your talk in an open space as far away from buildings as possible, as this improves your projection techniques. Additionally, the clean air will allow breathing to slow in pace with the outdoors, and you’ll speak at a slower and more articulate pace.
However, the most important factor of this is that just going over the speech in the natural, green environment itself will act as a vital element in calming your mind and reducing your nerves.
This element of calm can then be drawn upon when you are presenting, simply through breathing deeply and imagining the garden environment, allowing you to think straight and present clearly.”
