Three tips for dealing with public speaking nerves:
The presentation: rehearse, record yourself and get some feedback from someone you can trust. The more familiar you are with it all, the more confident you’ll feel on the day.
Your body: relax your shoulders, stand straight and easy, control your breathing – focus on breathing from your diaphragm, not from your chest.
Your mind: remember they want you to succeed – so smile and make eye contact. They’ll like you for it.
