How to improve my acting skills (really long sorry!)??????

The trick to being confident is having that "I Don't Care What People Think" attitude. Speak loudly and clearly. Just go out there and do what you love to do as if nobody is watching you. When people see you on stage or wherever you may be, they'll watch you in admiration and maybe even be a little jealous of you and how confident you are. Don't let the fear of people making fun of you ruin your dream of becoming an actor. Who are they to make fun of you? What makes them so special? Acting is your future and don't let anybody stand in your way. Something else that can boost confidence is recording yourself acting performing a monologue on your web cam or any other camera you have and share it with other people who want to be actors too such as a place like http://www.HowsMyActing.com - it's a social network and video sharing site for actors and aspiring actors. Make some friends there :)

I agree with Nick

the only thing that will really do you any good is to be in all the plays you can find to be in., this is no time to think of Method Acting, just do the parts, If you are tired of being a loser, find something you are good at and do that. Maybe it is not acting, maybe it is drawing and painting, maybe it is cooking and baking, maybe it is writing stories and poetry. Whatever it is, it should be something that is really fun to do.
