Fear is both a physiological challenge and a psychological one. Anything competitive — like sports events, war, or being compared by an audience with other speakers they have already heard — inspires the mobilization of personal resources to succeed. While you are working to improve your physical resilience, you need to also turn to the arena of psychology, emotions, practice, and delivery to build your skills. The more self-confidence you have, the less fear you are likely to experience at the podium.
