Steven Pressfield, the author of The War Of Art, one of my favorite books, once said:
“The amateur believes he must first overcome his fear; then he can do his work. The professional knows that fear can never be overcome.”
Since you’re a professional, you know what Pressfield knows: nothing conquers fear quite like taking action.
Acknowledge the fear, then set it aside and get to work.
This goes double for public speaking. Your audience wants to hear from you. Your duty is to speak to them. You will never stop feeling fear, so learn how to deliver your message anyway.
