When I was in college, I was terrified of public speaking. I used to win best actress awards at inter-collegiate drama competitions. But even if I had to deliver a small ‘thank you’ speech, my legs would turn to jelly; I would break into a sweat and even throw up. But then I started writing down my speech and practiced it in front of the mirror, just like I rehearsed my lines. I overcame my terror (wouldn’t call it evil) and today, I am comfortable in front of a mike. I believe practice and experience help, provided you are determined to overcome your limitation.
