what to do for lack of confidence??????????

Ya you are absolutely correct, its due to lack of confidence. You need some experience to do it. For help try to get help from your friends to help you get a demo speech practice. Or when you are with friends then you try to stand in front of them and tell something. Its on you, you have to make your mind to cope with the situation so that you can get the confidence from within you. FEEL AS IF YOU CARE FOR NOTHING, NO ONE CAN HARM YOU AND YOU ARE CARELESS.

well just believe in urself..and breath deeply..keep smilin.. always think that u r good..
