D, make friends with the lady. Sincerely find out about her.
It is true that confidence has an affect on people. Women like confident men. Men like confident women. People like confident people.
What do you do in your life that you are proud of? Where do your interests and talents lie? I knew a guy who wooed a woman he met in a camera/photography club. He was asking everyone if they knew where he could buy film for a certain odd camera. He was an American in England. She was British. She told him she knew where he could find the film. He used this as a stepping off point to get to know her better, doing something they both found interesting: photography. As they worked together on the club assignments, he got to know her better and a romance bloomed. They dated, fell in love and stayed married until his death a few years back. He was over ten years older than her.
The best relationships I have had stemmed from becoming friends with guys I met while pursuing a common interest. With both, there was obvious mutual chemistry from the first meeting. We genuinely liked each other. But with both we were friends for a while before any romance started. It was so much fun getting to know them and watching the relationships unfold.
I bet if you meet someone who shares an interest that you do, you will feel more confident.
Some important things to keep in mind. Good grooming and hygiene, not forgetting your finger and toenails and teeth is paramount. Having clothing that is in good shape that fits you well is also important. When you care about yourself, it will help you have more confidence and it will show. Do you like wearing things like hats, jewelry, cool belts and shoes or boots? Do you have a handle on your own style personality?
Do you do things like make your own bbq sauce or play an instrument? Are you good at something like bowling or pool? Sculpture? Cooking? Be an interesting person. Like Napoleon Dynamite says, chicks like guys with skills.
