I checked your Myspace page and I agree, you could definitely pass for 10 years younger than your age.
Some people, Rawxstasy, will find that when they return a smile to an attractive person, it is actually quite difficult for that person not to respond in a positive way and open a dialogue.
You may find that you are easily and naturally able to adopt the attitude that one might be able to treat the encounter like an interview where you begin to have fun finding out if the person is a good match for you.
It's good fun to try new ways to explore your social encounters, isn't it?
Eventually, you will find the courage to make the first move and you will be amazed at how quickly you have already learned to be supremely confident in these situations.
