Well first and foremost you need to get out there and interact with others. Not so easy when your shy I know but with practice you can do it. Keep in mind all people are nervous when meeting new friends. Your not alone there. The worst that can happen is they wont be interested just shake it off and move on its there loss.
Good places to start … Shopping, coffee shops, clubs, religous groups or church depending on your affiliation. Of course Bars,
Now go out and find a friendly interesting target. Practice small talk and eye contact first. Learn to observe people, you can see there personality in their movements and expressions. You can also pick up on their interests so you will know what your openning line should be.
Lets start simple and go to the coffee shop for example… This is just a example you live in another country so you can apply it basically to your enviroment.
Get your coffee, Deep breath, Plant your butt near someone.
Now suppose they are eating a muffin and your not.
You could say, Hey that muffin looks interesting. How is it ?? Always end with a question at first this brings them into the conversation. Depending on what they anwser your going to respond.
Suppose they say…
HER: Yeah it is kinda dry.
YOU: Ah well good thing I didnt then. did you ever have the muffins over at BigBartsmufforama ??? ( I made that up LOL)
HER: no, if she is polite she will ask how they are.
Now you can start fishing for information…
YOU: Big barts is near my work, they are great, I am a mail carrier. What do you do ???
A conversation is born. See how if you end with a question it draws them in. Without the questions at first the convo fizzles out.
This technique is something you should practice alot. Smile, make eye contact when talking. Use a open body posture. All this projects confidence.
