Batash Self-trust is the first secret of success.Believe in urself that u can persuade the pplz around u and make urself comfortable to ur existing environment.If any person Appeals to u then just make a approach to the person with a smile and start a converstion with a greeting like "hi","hello" or if that person is a gal then just complimet with a word "u have a sweet smile" or "u look gr8 in this black dress" .Remember!!!!!! while complimenting, be specific,it helps to draw lil more attention of that person ....OR...u can begin ur converstion with some jokes.While u will be commmunicating , other person's body-attitude and responce to ur words will reflect that how much u are comfying him/her and how entertaining ur company is. Try to envolve other person equally to ur converstion .As Silence is sometimes the best answer,listen to the other person when she/he is talking.Trying too hard may irritate person so just be urself while u communicate.Let the conversation flow smooth and normal. Well, Self-trust is the essence of heroism.and with the span of time u will learn how to be intriguing and enthusiastic.As pplz say that "Sense comes with age". wish u all the best!!!!!!
